WHPX: register for unrecognized MSR exits
Some variations of Linux kernels end up accessing MSR's that the Windows Hypervisor doesn't implement which causes a GP to be returned to the guest. This fix registers QEMU for unimplemented MSR access and globally returns 0 on reads and ignores writes. This behavior is allows the Linux kernel to probe the MSR with a write/read/check sequence it does often without failing the access.
