spidernet: null out skb pointer after its been used.
Avoid kernel crash in mm/slab.c due to double-free of pointer.
If the ethernet interface is brought down while there is still
RX traffic in flight, the device shutdown routine can end up
trying to double-free an skb, leading to a crash in mm/slab.c
Avoid the double-free by nulling out the skb pointer.
