Revert "sit: stateless autoconf for isatap"

This reverts commit 645069299a1c7358cf7330afe293f07552f11a5d.

While the code does not actually break anything, it does not completely follow
RFC5214 yet. After talking back with Fred L. Templin, I agree that completing the
ISATAP specific RS/RA code, would pollute the kernel a lot with code that is better
implemented in userspace.

The kernel should not send RS packages for ISATAP at all.
