This fixes the NullReferenceException that occurs when trying to evacuate a host after a non-livepatch update (that requires reboot) has been installed

XenCenter will check host.patches_requiring_reboot when a host restart is due while a batch update is in progress. If the restart is not required, XenCenter will skip relevant PlanActions.
The intention here is to check this whenever a restart is due according to the original schedule - this way a completely livepatchable update can prevent the restart while the key batch hotfixing logic is not changed.
