ipwireless: Do not return value from sending funcs
ipwireless: Do not return value from sending funcs
Do not return value from do_send_fragment and do_send_packet, it's not used.
The packet size checks are not useful too:
* zero length packet will never be sent, caller always passes packet_header
size which is either 1 or 3
* MTU check is done in caller, no need to repeat
