ext4: move several mount options to standard handling loop

Browse Source 
Several mount option (resuid, resgid, journal_dev, journal_ioprio) are
currently handled before we enter standard option handling loop. I don't
see a reason for this so move them to normal handling loop to make things
more regular.
