ext4: Remove outdated comment about lock_super()
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. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
