net: shrinks struct net_device
commit ab95bfe01 (net: replace hooks in __netif_receive_skb) added
rx_handler at wrong place, between two cache line aligned objects,
creating a big hole (a full cache line)
Move rx_handler and rx_handler_data before rx_queue, filling existing
hole.
Move master field in the cache line(s) used in receive path.
This saves 64 bytes (or L1_CACHE_BYTES), and avoids two possible
cache misses in receive path.
