Like what _mount_delay does in common/dmdelay.

Calling _mount doesn't work when we want to add mount options such as realtime devices. Since it's just a normal scratch device mount except for the source device, just call _scratch_mount with SCRATCH_DEV set to the dmerror device. Signed-off-by: Darrick J.
