cxgb4: remove netdev_alloc_page and use __GFP_COLD

This patch removes 08-remove_netdev_alloc_page.patch since there are couple
of additional changes are required in cxgb4 driver apart from what this patch
does. It adds new cxgb4 driver patch with those additional changes.

The additional changes in cxgb4 driver are taken from upstream commit
