Giving it a proper name like this takes away the indication that this
situation is very special.
Two leading underscores to an interface means "something special and
unusual requiring more careful consideration than usual is occuring
here." netdev_alloc_skb_nowarn() on the other hand, does not
convey this meaning.
And we will have very few drivers that use this construct, thus it
really is best to handle things the way Andrew has.
