scsi: zero per-cmd driver data before each I/O
Without this drivers that don't clear the state themselves can see off
effects. For example Hyper-V VMs using the storvsc driver will often
hang during boot due to uncleared Test Unit Ready failures.
Fixes: e9c787e6 ("scsi: allocate scsi_cmnd structures as part of struct request")
