Johannes Berg ebef8ea2ba um: time-travel: Fix IRQ handling in time_travel_handle_message() 
As the comment here indicates, we need to do the polling in the
idle loop without blocking interrupts, since interrupts can be
vhost-user messages that we must process even while in our idle
loop.

I don't know why I explained one thing and implemented another,
but we have indeed observed random hangs due to this, depending
on the timing of the messages.

Fixes: 88ce64249233 ("um: Implement time-travel=ext")
