HV: Clear DM set guest_flags when shutdown vm

Browse Source 
Currently, the previous configurations about guest_flags set by DM will
not be cleared when shutdown the vm. Then it might bring issue for the
next dm-launched vm.

For example, if we create one vm with LAPIC_PASSTHROUGH flag and shutdown it.
Then the next dm-launched vm will has the LAPIC_PASSTHROUGH flag set no matter
whether we set it in DM.

This patch clears all the DM set flags when shtudown vm.
