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.
