net/xdp: set FOLL_PIN via pin_user_pages()
Convert net/xdp to use the new pin_longterm_pages() call, which sets
FOLL_PIN. Setting FOLL_PIN is now required for code that requires
tracking of pinned pages.
In partial anticipation of this work, the net/xdp code was already calling
put_user_page() instead of put_page(). Therefore, in order to convert
from the get_user_pages()/put_page() model, to the
pin_user_pages()/put_user_page() model, the only change required here is
to change get_user_pages() to pin_user_pages().
