nSVM: Test addresses of MSR and IO permissions maps

According to section "Canonicalization and Consistency Checks" in APM vol 2,
the following guest state is illegal:

    "The MSR or IOIO intercept tables extend to a physical address that
     is greater than or equal to the maximum supported physical address.
     The VMRUN instruction ignores the lower 12 bits of the address
     specified in the VMCB."

[Fix the test so that it passes when VMRUN does ignore the lower 12
 bits of the address. - Paolo]
