[PATCH] net: use 32-bit arithmetic while allocating net device

[Alexey Dobriyan]

Private part of allocation is never big enough to warrant size_t.

Space savings:

        add/remove: 0/0 grow/shrink: 0/1 up/down: 0/-10 (-10)
        function                                     old     new   delta
        alloc_netdev_mqs                            1120    1110     -10
