virtio_console: fix misc probe bugs
This fixes the following issue discovered by code review:
after vqs have been created, a buggy device can send an interrupt.
A control vq callback will then try to schedule control_work which has
not been initialized yet. Similarly for config interrupt. Further, in
and out vq callbacks invoke find_port_by_vq which attempts to take
ports_lock which also has not been initialized.
To fix, init all locks and work before creating vqs.
