RDMA: Add ib_virt_dma_to_page()
Make it clearer what is going on by adding a function to go back from the
"virtual" dma_addr to a kva and another to a struct page. This is used in the
ib_uses_virt_dma() style drivers (siw, rxe, hfi, qib).
Call them instead of a naked casting and virt_to_page() when working with dma_addr
values encoded by the various ib_map functions.
This also fixes the virt_to_page() casting problem Linus Walleij has been
chasing.
