SCSI fixes on 20170823

Browse Source 
Six minor and error leg fixes, plus one major change: the reversion of
 scsi-mq as the default.  We're doing the latter temporarily (with a
 backport to stable) to give us time to fix all the issues that turned
 up with this default before trying again.

---help---
This option enables the new blk-mq based I/O path for SCSI
devices by default. With the option the scsi_mod.use_blk_mq
module/boot option defaults to Y, without it to N, but it can
still be overridden either way.
If unsure say N.
