ext4: preserve the needs_recovery flag when the journal is aborted
commit 97abd7d4b5d9c48ec15c425485f054e1c15e591b upstream.
If the journal is aborted, the needs_recovery feature flag should not
be removed. Otherwise, it's the journal might not get replayed and
this could lead to more data getting lost.
