HV: life_mngr: refine platform shutdown when User VM fails to shutdown 

Currently, the lifecycle manager in Service VM will issue poweroff
command to shutdown service VM when User VM fails to shutdown. The
post-launched RTVM with virtio device may hang after Service VM
shutdown.

In this patch, the lifecycle manager in Service VM will stop to
shut down service VM when User VM fails to shutdown. Users have
chance to fix User VM shutdown failure (such as forcelly shutdown
User VM or execute poweroff command in User VM), after the failure
is fixed, user can trigger S5 in service VM to shutdown platform
gracefully.

Tracked-On: #6652
