[GFS2] Remove lock methods for lock_nolock protocol
GFS2 supports two modes of locking - lock_nolock for single node filesystem and lock_dlm for cluster mode locking. The gfs2 lock methods are removed from file operation table for lock_nolock protocol. This would allow VFS to handle posix lock and flock logics just like other in-tree filesystems without duplication. Signed-off-by: S.
