Remove unused patty_ax25_sock_flow_full()

Browse source 
Remove unused patty_ax25_sock_flow_full(), in favor of the previously
implemented patty_ax25_sock_flow_left(), as a better means of
determining what flow control measures to take and how to interrogate
the peer for readiness to receive with minimal overhead
