[PATCH] batman-adv: remove includes for extern declarations

[Sven Eckelmann <sven@narfation.org>]

It is not necessary to include the header for the struct definition for an
"extern " declaration. It can simply be dropped from the headers to reduce
the number of includes the preprocessor has to process. If needed, it can
be added to the actual C source file.
