pcnet: Drop pcnet_can_receive

Browse source 
pcnet_receive already checks the conditions and drop packets if false.
Due to the new semantics since 6e99c63 ("net/socket: Drop
net_socket_can_send"), having .can_receive returning 0 requires us to
explicitly flush the queued packets when the conditions are becoming
true, but queuing the packets when guest driver is not ready doesn't
make much sense.
