Andres Freund d40fd85187 lwlock: Remove support for disowned lwlwocks 
This reverts commit f8d7f29b3e, plus parts of
subsequent commits fixing a typo in a parameter name.

Support for disowned lwlocks was added for the benefit of AIO, to be able to
have content locks "owned" by the AIO subsystem. But as of commit fcb9c977aa,
content locks do not use lwlocks anymore.

It does not seem particularly likely that we need this facility outside of the
AIO use-case, therefore remove the now unused functions.

I did choose to keep the comment added in the aforementioned commit about
lock->owner intentionally being left pointing to the last owner.
