x86/PVH: avoid 32-bit build warning when obtaining VGA console info

commit aadbd07ff8a75ed342388846da78dfaddb8b106a upstream.

In the commit referenced below I failed to pay attention to this code
also being buildable as 32-bit. Adjust the type of "ret" - there's no
real need for it to be wider than 32 bits.
