Remove PRINT_FIELD_INET4_ADDR

Reduce code duplication by removing PRINT_FIELD_INET4_ADDR
and using PRINT_FIELD_INET_ADDR instead.

* print_fields.h (PRINT_FIELD_INET4_ADDR): Remove.
* msghdr.c (print_cmsg_ip_pktinfo): Use PRINT_FIELD_INET_ADDR
instead of PRINT_FIELD_INET4_ADDR.
* net.c (print_mreq): Likewise.
* sockaddr.c (print_sockaddr_data_in): Likewise.
