Revert "scsi: default to scsi-mq"
Defaulting to scsi-mq in 4.13-rc has shown various regressions on setups that we didn't previously consider. Fixes for them are in progress, but too invasive to make it in this cycle. So for now revert the commit that defaults to blk-mq for SCSI. For 4.14 we'll plan to try again with these fixes. This reverts commit 5c279bd9e40624f4ab6e688671026d6005b066fa.
