Convert straggling drivers to new six-argument get_user_pages()

Convert straggling drivers to new six-argument get_user_pages()

Commit ff3979cbac00 ("mm/gup: Switch all callers of get_user_pages() to
not pass tsk/mm") switched get_user_pages() callers to the simpler model
where they no longer pass in the thread and mm pointer.  But since then
we've merged changes to a few drivers that re-introduce use of the old
interface.  Let's fix them up.

They continued to work fine (thanks to the truly disgusting macros
introduced in commit dcb8304ed1f3: "mm/gup: Overload get_user_pages()
functions"), but cause unnecessary build noise.
