Alex Williamson ac2a9862b7 vfio-pci: Fix GTT wrap-around for Skylake+ IGD 
Previous IGD, up through Broadwell, only seem to write GTT values into
the first 1MB of space allocated for the BDSM, but clearly the GTT
can be multiple MB in size.  Our test in vfio_igd_quirk_data_write()
correctly filters out indexes beyond 1MB, but given the 1MB mask we're
using, we re-apply writes only to the first 1MB of the guest allocated
BDSM.

We can't assume either the host or guest BDSM is naturally aligned, so
we can't simply apply a different mask.  Instead, save the host BDSM
and do the arithmetic to subtract the host value to get the BDSM
offset and add it to the guest allocated BDSM.
