phosphor-state-manager: fix chassis poweroff calling wrong host stop

In multihost system, the OBMC_CHASSIS_INSTANCES contains "0" instance
id, which is not exist in OBMC_HOST_INSTANCES. It cause
obmc-chassis-poweroff calling wrong instance of obmc-host-stop in
multihost system.

Example of yosemite4:
- OBMC_CHASSIS_INSTANCES: 0,1,2,3,4,5,6,7,8
- OBMC_HOST_INSTANCES: 1,2,3,4,5,6,7,8

Change to use OBMC_HOST_INSTANCES for both obmc-chassis-poweroff and
obmc-host-stop.

Tested on yosemite4:
- before change, obmc-chassis-poweroff & obmc-host-stop mapping to the
  different instance id.
