af_packet produces lots of these:
net/packet/af_packet.c:384:39: warning: incorrect type in return
expression (different modifiers)
net/packet/af_packet.c:384:39: expected struct page [pure] *
net/packet/af_packet.c:384:39: got struct page *
this seems to be because sparse does not realize that _pure
refers to function, not the returned pointer.
Tweak code slightly to avoid the warning.
