[B.A.T.M.A.N.] [PATCH 2/4] batman-adv: silence uninitialized variable warning

[Simon Wunderlich <sw@simonwunderlich.de>]

From: Simon Wunderlich <simon@open-mesh.com>

sparse (at least the version of the build checker) is complaining about:

routing.c: In function 'batadv_find_router':
routing.c:431:28: warning: 'next_candidate_router' may be used
uninitialized in this function [-Wmaybe-uninitialized]

Although this is bogus, silencing is not expensive and is done by this
patch.

Introduced by 797edd9e87ac838711e03498a4ae795b600191af
("batman-adv: add bonding again")
