Staging: batman-adv: Remove hashdata_compare_cb from hash
Function pointers cannot be inlined by a compiler and thus always has
the overhead of an call. hashdata_compare_cb's are one of the most often
called function pointers and its overhead must kept relative low.
As first step, every function which uses this function pointer takes it
as parameter instead of storing it inside the hash abstraction
structure.
This not generate any performance gain right now. The called functions
must also be able to be inlined by the calling functions to enable
inlining of the function pointer.
