This reverts commitf8d7f29b3e, 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 commitfcb9c977aa, 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.
