This patchset updates certain drivers that incorrectly size their internal
buffers to hold the page DMA addresses while iterating the DMA-mapped umem SGL.
It is a precursor series to adding page combining for umem SGLs.

v0->v1:
*Use ib_umem_num_pages() accessor as opposed to umem->npages
to size the buffers.
