To avoid duplication and simplify implementation, we remove gfs2 lock
method (gfs2_lock and gfs2_flock) from file operation table for
lock_nolock protocol. This would allow VFS layer to handle posix and
flock logics like any other in-tree filesystem. The existing
implementation has few issues that would fail NFS connectathon test
(cthon04).
