When the added page is merged to last same page in bio_add_pc_page(), the user may need to put this page for avoiding page leak. bio_map_user_iov() needs this kind of handling, and now it deals with it by itself in hack style. Moves the handling of put page into __bio_add_pc_page(), so bio_map_user_iov() may be simplified a bit, and maybe more users can benefit from this change.
