Subject: [PATCH] jbd2: fix commit code to properly abort journal

From: Jan Kara <jack@...e.cz>

We should really call journal_abort() and not __journal_abort_hard() in
case of errors.  The latter call does not record the error in the journal
superblock and thus filesystem won't be marked as with errors later (and
user could happily mount it without any warning).
