KVM: VMX: Pass cr0.mp through to the guest when the fpu is active
When cr0.mp is clear, the guest doesn't expect a #NM in response to
a WAIT instruction. Because we always keep cr0.mp set, it will get
a #NM, and potentially be confused.
Fix by keeping cr0.mp set only when the fpu is inactive, and passing
it through when inactive.
