scsi: vmw_pvscsi: Expand vcpuHint to 16 bits

[ Upstream commit cf71d59c2eceadfcde0fb52e237990a0909880d7 ]

vcpuHint has been expanded to 16 bit on host to enable routing to more
CPUs. Guest side should align with the change. This change has been tested
with hosts with 8-bit and 16-bit vcpuHint, on both platforms host side can
get correct value.
