Fix KVM's long-standing buggy handling of SVM's exit_code as a 32-bit
value. Per the APM and Xen commit d1bd157fbc ("Big merge the HVM
full-virtualisation abstractions.") (which is arguably more trustworthy
than KVM), offset 0x70 is a single 64-bit value:
070h 63:0 EXITCODE
Track exit_code as a single u64 to prevent reintroducing bugs where KVM
neglects to correctly set bits 63:32.
Fixes: 6aa8b732ca01 ("[PATCH] kvm: userspace interface")
