[PATCH net-next 06/15] batman-adv: drop unneeded goto and initialization from batadv_hardif_disable_interface()

[Simon Wunderlich <sw@simonwunderlich.de>]

From: Nora Schiffer <neocturne@universe-factory.net>

The only use of the label was too early for primary_if to be set
anyways.

Also move the put of primary_if further up to hold the reference only as
long as necessary, hopefully avoiding the need to re-introduce the goto
label with future code changes.
