KVM: x86: Store gpa as gpa_t, not unsigned long, when unprotecting for retry
Store the gpa used to unprotect the faulting gfn for retry as a gpa_t, not
an unsigned long. This fixes a bug where 32-bit KVM would unprotect and
retry the wrong gfn if the gpa had bits 63:32!=0. In practice, this bug
is functionally benign, as unprotecting the wrong gfn is purely a
performance issue (thanks to the anti-infinite-loop logic). And of course,
almost no one runs 32-bit KVM these days.
