socks: use the right function when printing struct openvpn_sockaddr

socks: use the right function when printing struct openvpn_sockaddr

57623b4e introduced a print_sockaddr() call in socks.c to print an
openvpn_sockaddr object.

However, this is not correct because print_sockaddr() expects a sockaddr
object as argument instead of openvpn_sockaddr.

This error did not lead to any issue because the two objects are very
similar in regards to the data accessed by print_sockaddr().

Fix this by replacing print_sockaddr() with print_openvpn_sockaddr().
