[PATCH 2/2] goldfish_pipe/mm: convert to the new put_user_page() call

[john . hubbard]

From: John Hubbard <jhubb...@nvidia.com>

For code that retains pages via get_user_pages*(),
release those pages via the new put_user_page(),
instead of put_page().

Also: rename release_user_pages(), to avoid a naming
conflict with the new external function of the same name.
