net/9p: Add multi channel support.
This is needed for supporting multiple mount points.
We can find out the device names to be used with mount by checking
/sys/devices/virtio-pci/virtio*/device file
if the device file have value 9 then the specific virtio device can
be used for mounting.
ex:
#cat /sys/devices/virtio-pci/virtio1/device
9
now we can mount using
# mount -t 9p -o trans=virtio virtio1 /mnt/
