[B.A.T.M.A.N.] [PATCH 1/2] batman-adv: use batadv_compare_eth when possible

[Sven Eckelmann <sven@narfation.org>]

From: Antonio Quartulli <a@unstable.cc>

When comparing Ethernet address it is better to use the more
generic batadv_compare_eth. The latter is also optimised for
architectures having a fast unaligned access.

Patch was resurrected from https://patchwork.open-mesh.org/patch/3668/

I've requested an rebased version at
https://lists.open-mesh.org/pipermail/b.a.t.m.a.n/2016-March/014639.html
but done it myself because it was rather trivial.
