[PATCH] net: make struct napi_alloc_cache::skb_count unsigned int

[Alexey Dobriyan]

size_t is way too much for an integer not exceeding 64.

Space savings: 10 bytes!

        add/remove: 0/0 grow/shrink: 0/3 up/down: 0/-10 (-10)
        function                                     old     new   delta
        napi_consume_skb                             165     163      -2
        __kfree_skb_flush                             56      53      -3
        __kfree_skb_defer                             97      92      -5
        Total: Before=154865639, After=154865629, chg -0.00%
