gfs2: properly initial file_lock used for unlock.
Rather than assuming all-zeros is sufficient, use the available API to initialize the file_lock structure use for unlock. VFS-level changes will soon make it important that the list_heads in file_lock are always properly initialized. Signed-off-by: NeilBrown <neilb@suse.com> Reviewed-by: J.
