[PATCH v3 09/17] common/dmerror: fix mount option issues

[Darrick J. Wong]

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.

v2: Use the standard _scratch_options for mounting.
