batman-adv: send GW_DEL event when the gw client mode is deselected
Whenever the GW client mode is deselected, a DEL event has
to be sent in order to tell userspace that the current
gateway has been lost. Send the uevent on state change only
if a gateway was currently selected.

batman-adv: check return type of unicast packet preparations
batadv_unicast(_4addr)_prepare_skb might reallocate the skb's data.
And if it tries to do so then this can potentially fail.
We shouldn't continue working on this skb in such a case.
