net: usb: Remove disruptive netif_wake_queue in rtl8150_set_multicast

syzbot reported WARNING in rtl8150_start_xmit/usb_submit_urb.
This is the sequence of events that leads to the warning:

rtl8150_start_xmit() {
	netif_stop_queue();
	usb_submit_urb(dev->tx_urb);
}

rtl8150_set_multicast() {
	netif_stop_queue();
	netif_wake_queue();		<-- wakes up TX queue before URB is done
}

rtl8150_start_xmit() {
	netif_stop_queue();
	usb_submit_urb(dev->tx_urb);	<-- double submission
}

rtl8150_set_multicast being the ndo_set_rx_mode callback should not be
calling netif_stop_queue and notif_start_queue as these handle
TX queue synchronization.

The net core function dev_set_rx_mode handles the synchronization
for rtl8150_set_multicast making it safe to remove these locks.
