doc: change the parameter of virtio-net

Remove device name requirement for “tap” and "vmnet", change the
parameter format like:
"-s 4,virtio-net,tap/vmnet=dev_name".
change mac_seed to virtio-net sub-parameter
As a parameter of acrn-dm,the mac_seed is only used for virtio-net.
So this patch change it to the sub-parameter of virtio-net.
The final format is:
-s 4,virtio-net,tap/vmnet=dev_name,mac_seed=XXXX
