[B.A.T.M.A.N.] [PATCH maint 2/2] batman-adv: fix var name to keep compatibility with old kernels

[Antonio Quartulli <antonio@meshcoding.com>]

The first argument of kfree_rcu() is used in compat.h to forge
a function name used by old kernels. Keep it as it was before
to avoid breaking this compat mechanism.

Introduced by 9729d2085c0fa4398eb1ee518b0097866dfdcd77
("batman-adv: fix TT VLAN inconsistency on VLAN re-add")
