Sven Eckelmann 95d8f85c91 batman-adv: Improve includes for trace functionality
The batadv_dbg trace event uses different functionality and datastructures
which are not directly associated with the trace infrastructure. It should
not be expected that the trace headers indirectly provide them and instead
include the required headers directly.
