THIS_MODULE is used to differentiate modules on Linux. We currently
completely stub out any Linux struct module usage, but THIS_MODULE
is still used to populate the "owner" fields of various drivers.
Even though we don't actually dereference these "owner" fields they
are still used by drivers to check if devices/dmabufs/etc come
from different modules. For example, during DRM GEM import some
drivers check if the dmabuf's owner matches the dev's owner. If
they match because they are both NULL drivers may incorrectly think
two resources come from the same module.
This adds a general purpose __this_linker_file which will point to
the linker file of the module that uses it. We can then use that
pointer to have a valid value for THIS_MODULE.

if_private.h details. Adjust the code to no longer depend on internal
details of ifnet. We also switch the "check"-functionn from if_init to
if_transmit which we can query. Given we do have a per-vif eventhandler
we could do without that check but would still need to check
if_getflags() for IFF_UP.

rtw89 TX path was faulting in linuxkpi_ieee80211_next_txq() due to a
"double scheduling" check in linuxkpI_ieee80211_schedule_txq() being
incorrect:
the next pointer may be NULL there if the element is the last in the
tailq, so correctly check tqe_prev. Without the fix we may have queued
the same element to the tailq twice, and because it was the last element
and had a NULL tqe_next, that NULL value would get propogated into
another node's tqe_prev on removal, and other such nastiness.

Native Linux implementation sets this as a maximum between 1 and
ht/vht/eht rx SS'es, FreeBSD does the same, but uses 0 as a minimum,
which leads setting it to 0 if we're not in ht/vht case.
This 0 was breaking rtw89 driver, when it was trying to determine
SS number by subtracting 1 from rx_nss and passing the value to the
hardware.
After this patch rtw89 association and simple ping work reliably,
but more work is needed to make the driver robust with heavy traffic
(iperf3) and being long idle.

Trying to use lindebugfs for debugging wirless drivers two issues
became apparent:
(a) a panic in lindebugfs calling a hard coded release function if the
caller had not provided one. This seems to be based on assumptions
that no longer hold up. Remove the hard coded release function to
prevent panics.
(b) In LinuxKPI simple_read_from_buffer() would call copy_to_user() but
buffers weren't setup for this (lindebugfs copies data from its
own buffer) and then pseudofs will do another copyout to the user
on this; remove the copy_to_user() and simply copy the data over
to the provided buffer; this works for as long as the only consumers
remain debugfs callers (which currently seems to be the case).
[the only out-of-tree consumers I am aware off are two drm-kmod
drivers/gpu/drm/amd/pm/* debugfs functions I cannot test].
