net: nixge: Use GFP_KERNEL instead of GFP_ATOMIC when possible 

NIXGE_MAX_JUMBO_FRAME_SIZE is over 9000 bytes and RX_BD_NUM 128.

So this loop allocates more than 1 Mo of memory.

Previous memory allocations in this function already use GFP_KERNEL, so
use __netdev_alloc_skb_ip_align() and an explicit GFP_KERNEL instead of a
implicit GFP_ATOMIC.

This gives more opportunities of successful allocation.
