Long NetVM shutdown is caused by PCI backend -> PCI frontend communication timeout - VM kernel is dead at that stage. Since we don't use PCI passthrough for any essential device there, we can simply detach them before initiating shutdown.

Thanks HW42 for the idea.

@marmarek
core: detach PCI devices before shutting down VM 
When VM is shutting down it doesn't disconnect PCI frontend (?), so when
VM is destroyed it ends up in timeouts in PCI backend shutdown (which
can't communicate with frontend at that stage). Prevent this by
detaching PCI devices while VM is still running.
