ip: fix problem on mips64 n64 big endian musl systems
Use designated initializers for struct msghdr. The struct layout is non-portable and musl libc does not match what busybox expects. Signed-off-by: Szabolcs Nagy <nsz@port70.net> Tested-by: Waldemar Brodkorb <wbx@openadk.org> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
