btl_tcp_proc.c: add missing "continue"

Also add another (superflous but symmetric) continue statement.

This missing "continue" statement allows IPv4 "private network"
matches to fall through and allow IPv6 matches to be made -- thereby
overriding the IPv4 match that was already made.

Fixes #585 (although several of the other issues identified on #585
still exist, the primary / initial bug that was reported there is now
fixed).
