lockd: ensure we use the correct file descriptor when unlocking

[ Upstream commit 69efce009f7df888e1fede3cb2913690eb829f52 ]

Shared locks are set on O_RDONLY descriptors and exclusive locks are set
on O_WRONLY ones. nlmsvc_unlock however calls vfs_lock_file twice, once
for each descriptor, but it doesn't reset fl_file. Ensure that it does.
