When looping through addrinfo lists in AddrsMatch, keep a copy of the
original addrinfo pointers to free instead of ending up at the terminating
NULLs and trying to free those.
OpenWRT uses musl in which freeaddrinfo(NULL) is not safe (which is
fine, it's not required by the spec) so this fixes a segfault.
