Subject: [PATCH 05/24] Remove obsolete function in6_fillscopeid

This seems to be an old remnant from the very early days of IPv6
when the kernel would include the ifindex in the link-local
addresses returned by getifaddrs(). This is no longer the case on
Linux, so the code is a no-op.

A no-op that makes gcc throw warnings about illegal type-punning.
