The first two patches remove local_irq_save() around
`netdev_alloc_cache' which does not work on -RT. Besides helping -RT it
whould benefit the users of the function since they can avoid disabling
interrupts and save a few cycles.
The remaining patches are from a time when I tried to remove
`netdev_alloc_cache' but then noticed that we still have non-NAPI
drivers using netdev_alloc_skb() and I dropped that idea. Using
napi_alloc_frag() over netdev_alloc_frag() would skip the not required
local_bh_disable() around the allocation.
