[vfio-users] Host can't wake from suspend after running a passthrough VM

After I start and then shutdown my passthrough VM and then suspend the
host, it won't wake from suspend anymore. As in, once in S3, pressing
the power button simply has no effect. I have to press the reset
button (and sometimes that doesn't work either) and restart the
machine. Suspend works correctly if I never start the VM.

Has anyone seen this issue before?
