[B.A.T.M.A.N.] [PATCH 2/2] batman-adv: Fix build of batman-adv without BLA

[Sven Eckelmann <sven@narfation.org>]

4c1721b39c8a77c99e8f4de97b5d5d112006406c ("batman-adv: Fix potential broadcast
BLA-duplicate-check race condition") introduced a spinlock for bridge loop
avoidance which was initialized outside of bla. This causes an build error when
BLA is disabled. Instead the batadv_bla_init function should handle the
initialization.
