Michael S. Tsirkin ee7fb5b371 virtio_console: avoid config access from irq ...

[ Upstream commit eeb8a7e8bb ]

when multiport is off, virtio console invokes config access from irq
context, config access is blocking on s390.
Fix this up by scheduling work from config irq - similar to what we do
for multiport configs.
