x86/AMD: Inject #GP instead of #UD when unable to map vmcb
According to AMD Programmer's Manual vol2, vmrun, vmsave and vmload
should inject #GP instead of #UD when unable to access memory
location for vmcb. Also, the code should make sure that L1 guest
EFER.SVME is not zero. Otherwise, #UD should be injected.
