While converting rapidio from get_user_pages() to pin_user_pages(),
I noticed a small problem in the error handling, so that is fixed
first. As such, the fix has -stable on CC, and can be separately
applied.

Note that I have only compile-tested these patches, although that does
also include cross-compiling for half a dozen arches.

  rapidio: fix an error in get_user_pages_fast() error handling
  rapidio: convert get_user_pages() --> pin_user_pages()
