inmates: apic-demo: Plug race around message evaluation
If msg_to_cell was not JAILHOUSE_MSG_SHUTDOWN_REQUEST, we took the
default path which also sent back JAILHOUSE_MSG_UNKNOWN - and cleared
msg_to_cell before that. This created a race condition with the
hypervisor trying to sent the cell a message. Due to the hlt, the race
normally didn't matter so far. It will when moving to polling-based
idle.

inmates: apic-demo: Use polling idle to avoid latency spikes
It has been observed and also confirmed by Intel that hlt can cause
wake-up delay in the order of microseconds, although no particular power
management is requested this way. That's obviously because of
unpredictable decisions of the CPU how to react on that internally.
As the apic-demo is (also) about demonstrating the minimal possible
interrupt delay, switch to polling.
