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
