[GFS2] Put back semaphore to avoid umount problem
Dave Teigland fixed this bug a while back, but I managed to mistakenly remove the semaphore during later development. It is required to avoid the list of inodes changing during an invalidate_inodes call. I have made it an rwsem since the read side will be taken frequently during normal filesystem operation. The write site will only happen during umount of the file system. Also the bug only triggers when using the DLM lock manager and only then under certain conditions as its timing related.
