Subject: [PATCH -next v2 2/2] ext4: adjust fast commit disable judgement order in ext4_fc_track_inode

If fastcommit is already disabled, there isn't need to mark inode ineligible.
So move 'ext4_fc_disabled()' judgement bofore 'ext4_should_journal_data(inode)'
judgement which can avoid to do meaningless judgement.
