[PATCH] X86EMU: pass the correct bus:dev:fn tag to pci emulation

[Bart Trojanowski]

When in x86emu, the PCI emulation routines were being given the TAG of
the video device regardless of what the BIOS code that is being emulated
asked for.

This patch uses the bus:dev:fn numbers that were passed to 0xCF8 when
calling the pciRead*() and pciWrite*() functions after an access to
0xCFC.
