From: Geliang Tang <tanggeliang@xxxxxxxxxx>
The types "sotype | SOCK_NONBLOCK" are passed to socket_loopback_reuseport
by some tests in sockmap_listen.c, so they must be handled in helper
start_server_addr() too.
This patch uses SOCK_TYPE_MASK to clear useless bits of "type" before check
whether it supports listen for connections.
