PVSCSI implementation in VMware hypervisor under specific configuration

disk geometry. It can be recognized by the kernel message:
[    0.776588] sd 1:0:0:0: [sdb] Sector size 0 reported, assuming 512.

PVSCSI implementation in QEMU does not set dataLen at all keeping it zeroed,
leading to the boot hang, as was reported by Shmulik Ladkani.

Applied to 5.16/scsi-fixes, thanks!
