vfs: vn_alloc(): Stop always calling vn_alloc_hard() and direct reclaiming 
Commit ab05a1cf32 intended to revert commit 8733bc277a
("vfs: don't provoke recycling non-free vnodes without a good reason"),
but due to intervening changes in commit 054f45e026 ("vfs: further
speed up continuous free vnode recycle"), it also had to revert part of
it.  In particular, while removing the whole 'if (vn_alloc_cyclecount !=
0)' block, it inadvertantly removed the code block resetting
'vn_alloc_cyclecount' to 0 and skipping direct vnode reclamation (done
further below through vnlru_free_locked_direct()), which had been
outside the 'if' before the intervening commit.

Removing this block instead of reinstating it in practice causes
'vn_alloc_cyclecount' to (almost) never be 0, making vn_alloc() always
call vn_alloc_hard(), which takes the 'vnode_list_mtx' mutex.  In other
words, this disables the fast path.  [The reverted commit, which
introduced the 'if (vn_alloc_cyclecount != 0)' guarding this block,
actually never executed it because it also had the bug that
'vn_alloc_cyclecount' would always stay at 0, hiding its usefulness.]

Additionally, not skipping direct vnode reclamation even when there are
less vnodes than 'kern.maxvnodes' not only causes unnecessary contention
but also plain livelocks as vnlru_free_locked_direct() does not itself
check whether there are actually "free" (not referenced) vnodes to be
deallocated, and will blindly browse all the vnode list until it finds
one (which it may not, or only a few ones at the end).  As the fast path
was disabled, all threads in the system would soon be competing for the
vnode list lock, outpacing the vnlru process that could never actually
recycle vnodes in a more agressive manner (i.e., even if they have
a non-zero hold count).  And we could more easily get into this
situation, as each vnode allocation was reducing the count of "free"
vnodes, even if entirely new vnodes could be allocated instead.  This
part was mitigated by the vnlru process (before the tipping point
described above), which explains why the mechanism would not always
livelock.

Not skipping direct vnode reclamation was arguably a bug introduced by
the intervening commit (054f45e026), but was mitigated by
vn_alloc_hard() not being called in the fast path.  The revert commit,
by disabling the fast path, made it significantly annoying (to the point
of getting a few livelocks a week in some of my workloads).

Restore the reset of 'vn_alloc_cyclecount' to 0 and skip direct
reclamation when the current number of vnodes is below the
'kern.maxvnodes' limit, indicating we can start allocating a new 'struct
vnode' right away.  While here, fix the comparison with the limit when
'bumped' is true.
