batman-adv: use atomic_xchg() for gw.reselect check

Browse Source 
batadv_gw_election() only needs to test whether gw.reselect was set and
clear it afterwards. Replace the batadv_atomic_dec_not_zero()
[atomic_add_unless(..., -1, 0)] call with atomic_xchg(..., 0) to simplify
the logic and make the intent more explicit.
