vfio/pci-quirks.c: Disable stolen memory for igd VFIO

Regardless of running in UPT or legacy mode, the guest igd
drivers may attempt to use stolen memory, however only legacy
mode has BIOS support for reserving stolen memmory in the
guest VM. We zero out the stolen memory size in all cases,
then guest igd driver won't use stolen memory.
In legacy mode, user could use x-igd-gms option to specify the
amount of stolen memory which will be pre-allocated and reserved
by bios for igd use.
