For an inode just changed authority, if the new auth MDS want to
change a lock in the inode from 'sync' to 'lock' state before caps
are exported. The lock in replica can be in 'sync->lock' state
because client caps prevent it from transitting to 'lock' state.
So we should call eval() after clearing client caps.
