ufs: kill lock_ufs()
There were 3 remaining users; in two of them we took ->s_lock immediately after lock_ufs() and held it until just before unlock_ufs(); the third one (statfs) could not be called from itself or from other two (remount and sync_fs). Just use ->s_lock in statfs and don't bother with lock_ufs at all. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
