net: remove netdev_alloc_page and use __GFP_COLD
Given we dont use anymore the struct net_device *dev argument, and this
interface brings litle benefit, remove netdev_{alloc|free}_page(), to
debloat include/linux/skbuff.h a bit.
(Some drivers used a mix of these interfaces and alloc_pages())
When allocating a page given to device for DMA transfer (device to
memory), it makes sense to use a cold one (__GFP_COLD)
