Vitaly Mayatskikh 399c46095e fix unbalanced page refcounting in bio_map_user_iov ...

commit 95d78c28b5 upstream.

bio_map_user_iov and bio_unmap_user do unbalanced pages refcounting if
IO vector has small consecutive buffers belonging to the same page.
bio_add_pc_page merges them into one, but the page reference is never
dropped.
