The writeback error handling test requires that you put the journal on a separate device. This allows us to use dmerror to simulate data writeback failure, without affecting the journal. xfs already has infrastructure for this (a'la $SCRATCH_LOGDEV), so wire up the ext4 code so that it can do the same thing when _scratch_mkfs is called.
