Zhenyu Wang 8704e89349 vfio/pci: Fix OpRegion read
This is to fix incorrect pointer arithmetic which caused wrong
OpRegion version returned, then VM driver got error to get wanted
VBT block. We need to be safe to return correct data, so force
pointer type for byte access.

Fixes: 49ba1a2976 ("vfio/pci: Add OpRegion 2.0+ Extended VBT support.")
