net: skbuff: update comment about pfmemalloc propagating
__skb_fill_page_desc_noacc() is not doing any pfmemalloc
propagating, and yet it has a comment about that, commit
84ce071e38
("net: introduce __skb_fill_page_desc_noacc")
may have accidentally moved it to __skb_fill_page_desc_noacc(),
so move it back to __skb_fill_page_desc() which is supposed
to be doing pfmemalloc propagating.
