busybox: fix uninitialized memory when displaying IPv6 addresses
After commit 8e74adab0107658e3dc04ed342206272a284f43e
("libbb: make INET[6]_rresolve use sockaddr2{host,dotted}_noport")
INET_sprint6 uses more than just sin6_addr, it also tries to display the
scope id, which is uninitialized when called from ife_print6.
