Due to the (late) point in time when qemu requests the hypervisor to
set up MSI-X interrupts (which is where the MMIO intercept gets put
in place), the hypervisor doesn't see all guest writes, and hence
shouldn't make assumptions on the state the virtual MSI-X resources
are in.

1: honor all mask requests
2: add valid bits for read acceleration
