[PATCH] net: net_utils: Move ip_to_string to lib/net_utils.c

[Adriano Cordova <adrianox@gmail.com>]

The function string_to_ip is already in net_utils, which is
compiled unconditionally, but ip_to_string is currently only
accessible if the legacy network stack is selected. This
commit puts ip_to_string in net_utils.c and removes it from the
legacy network code.
