ext4: warn on read-only filesystem in ext4_journal_check_start()

Now that filesystem abort marks the filesystem as shutdown, we shouldn't
be ever hitting the sb_rdonly() check in ext4_journal_check_start().
Since this is a suitable place for catching all sorts of programming
errors, convert the check to WARN_ON instead of dropping it.
