mavlink_mission: respect integer MAV_CMD in ROI settings as well
mavlink_mission: respect integer MAV_CMD in ROI settings as well

Otherwise the conversion from mavlink_mission_item to mission_item
will cause the latitude and longitude of the ROI to be off by a factor of 1e7
in the case of INT mode.
