hv: reset VM ioreqs in reset_vm

ioreqs acrossing VM reset is meaningless. So we reset their status when
VM reset.
Please note, device model and service os need to handle various ioreqs
pending status in emergency reset condition carefully. Otherwises, the
post processing of such ioreqs might overwrite this reset.
