ixgbe: use scattered Rx with bulk allocation

Simply initialze rx_pkt_burst callback to ixgbe_recv_pkts_lro_bulk_alloc()

This is possible because work against HW in LRO and scattered cases is

This warning is now disabled (commit <insertlater>) for old versions of GCC,

These initializers should not be needed for static variables but they
