correct netdever Accept() prototype

According to man page accept(2), accept returns new client sockfd and
remote peer ip:port.  This patch corrects the Accept() prototype in the
netdever interface to not take in an ip:port arg, but rather return an
ip:port for remote peer.

Tested with examples/net/tcpecho on wioterminal and nano-rp2040.  Here's
a run with wioterminal:
