Sören Tempel 85296ce6cc sock_dns: Fix incorrect buffer bounds check
Apart from advancing the buffer by RR_TYPE_LENGTH, RR_CLASS_LENGTH,
and RR_TTL_LENGTH the code also attempts to read a two byte unsigned
integer using _get_short(bufpos):

	unsigned addrlen = ntohs(_get_short(bufpos));

The bounds check must therefore ensure that the given buffer is large
enough to contain two more bytes after advancing the buffer.
