ext4: Remove outdated comment about lock_super()

Browse Source 
ext4_fill_super() is no longer called by read_super(), and it is no
longer called with the superblock locked.  The
unlock_super()/lock_super() is no longer present, so this comment is
entirely superfluous.

* akpm: core read_super() calls in here with the superblock locked.
* That deadlocks, because orphan cleanup needs to lock the superblock
* in numerous places. Here we just pop the lock - it's relatively
* harmless, because we are now ready to accept write_super() requests,
* and aviro says that's the only reason for hanging onto the
* superblock lock.
