[B.A.T.M.A.N.] [PATCH 4/4] 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.
