From: Radovan Prodanovic <radovan.prodano...@mitel.com>
Tests shows that it takes more than 10ms for __sock_create with
AF_INET6 returning failure if CONFIG_IPV6 is not set
The fix checks this case and make it exit with not supporting
error before calling request_module
if 'CONFIG_MODULE=y' and 'CONFIG_IPV6 is not set'
socket(AF_INET6, SOCK_STREAM, 0) can trigger this issue
