Bug 997: Fix unlikely stack corruption in get_pasv_socket.

Browse Source 
It is unlikely because the standard members of struct sockaddr_in
(sin_family, sin_port, sin_addr) already require at least 8 bytes
and I don't know of any system that has size_t larger than that.
Besides, at least glibc pads the structure to 16 bytes.
