[B.A.T.M.A.N.] [PATCH maint 1/2] Revert "batman-adv: free nf_bridge member on locally delivered skb"

[Antonio Quartulli <antonio@meshcoding.com>]

This reverts commit 9048eb62124f47f66d12eb1d706ab5fb265553f7.

This fix can be implemented using the nf_Reset() helper
instead of partly reimplementing it with a batman-adv
private function.
