  spapr-vscsi: fix CRQ status

Normally VIOSRP_OK (0) means success and non-zero value means error
except VIOSRP_OK2 (0x99) which is another success code by weird accident.

This uses 0 as success code always as some guests do not cope with
the 0x99 value well. The existing linux driver checks for both VIOSRP_OK
and VIOSRP_OK2 since 2.6.32.

This returns non-zero code (VIOSRP_ADAPTER_FAIL == 0x10) on errors which
can only happen if DMA write failed.

  scsi: Fix migration of scsi sense data

c5f52875 changed the size of sense array in vmstate_scsi_device by
mistake. This patch restores the old size, and add a subsection for the
remaining part of the buffer size. So that migration is not broken.

  virtio-scsi: actually honor sense_size from configuration space

We were always truncating the sense size to 96 bytes.
