Subject: [PATCH] e2fsck: exit journal recovery when find EIO, ENOMEM
 errors

jbd2_journal_revocer() may fail when some error occers
such as ENOMEM. However, jsb->s_start is still cleared
by func e2fsck_journal_release(). This may break
consistency between metadata and data in disk. Sometimes,
failure in jbd2_journal_revocer() is temporary but retry
e2fsck will skip the journal recovery when the temporary
problem is fixed.

To fix this case, we use "fatal_error" instead "goto errout"
when recover journal failed. If journal recovery fails, we
will send error message to user and reserve the recovery
flags to recover the journal when try e2fsck again.

Fix issue: https://gitee.com/src-openeuler/e2fsprogs/issues/I4RZUT?from=project-issue

conflict: journal_recover -> jbd2_journal_recover
