Staging: batman-adv: Don't allocate icmp packet with GFP_KERNEL
A new buffer for a packet is created when a icmp packet is received.
This happens in a context with disabled irq. Thus we are not allowed to
sleep or call function which might sleep. kmalloc must be called with
GFP_ATOMIC instead of GFP_KERNEL to ensure that it does not sleep.
