wifi: virt_wifi: free skb when disconnected
When the simulated link is disconnected, virt_wifi_start_xmit() returns
NET_XMIT_DROP without freeing the skb. dev_hard_start_xmit() treats this
return value as consumed, so every packet sent while disconnected leaks its
skb.
Free the skb before returning the drop status.
