[PATCH] quota: inode->i_flags locking fixes
The patch fixes locking of i_flags. It removes S_QUOTA flag from i_flags
because it was almost unused and updating it on some places correctly
(under i_sem) would be tricky. Note that accessing of S_NOQUOTA flag is
serialized by dqptr_sem and so we can reliably tested without i_sem.
