[ Upstream commit 9f27783b4dd235ef3c8dbf69fc6322777450323c ]
We currently do a lock_to_openmode call based on the arguments from the
NLM_UNLOCK call, but that will always set the fl_type of the lock to
F_UNLCK, and the O_RDONLY descriptor is always chosen.
Fix it to use the file_lock from the block instead.
