Binbin Wu f0d06165d3 hv: vmsr: handle guest msr ia32_misc_enable read/write 
Guest MSR_IA32_MISC_ENABLE read simply returns the value set by guest.
Guest MSR_IA32_MISC_ENABLE write:
- Clear EFER.NXE if MSR_IA32_MISC_ENABLE_XD_DISABLE set.
- MSR_IA32_MISC_ENABLE_MONITOR_ENA:
  Allow guest to control this feature when HV doesn't use this feature and hw has no bug.

vcpuid update according to the change of the msr will be covered in following patch.
