rpcapd: fix bogus error message buffer argument.

Probably a copy-and-pasteo; we were passing the result of
pcap_geterr(session->fp), which is the error buffer for the pcap_t being
used for the capture, to sock_send(), when we *should* have been using
the errbuf variable.

Fixes Coverity CID 1472849.
