Instead of trusting that struct file_lock returns completely unchanged
after vfs_test_lock() when there's no conflicting lock, stash away our
nlm_lockowner reference so we can properly release it for all cases.
This defends against another file_lock implementation overwriting fl_owner
when the return type is F_UNLCK.
