    _______________________________________________________

Details:

This patch fixes two warnings about unused variables.

One variable is completly unused as its switch-branch contains no code -- this
patch removes this branch which also removes the silent drop of certain
ND6-packets.

The other variable is only used in certain configurations. This patch encloses
its declaration and initialization in a suitable #if.

This patch makes LWIP completly warning free with my configuration and
compiler (apart from 3 "unreachble code"-warnings that come from
"break"-statements after a return from a switch-branch. I would consider them
good practice.
