Use the ib_umem_find_best_pgsz() and rdma_for_each_block() API when
registering an MR instead of coding it in the driver.

The dma_set_max_seg_size() has *nothing* to do with
ib_umem_find_best_pgsz() other than its value should be larger than the largest
set bit.

Again, it is supposed to be the maximum value the HW can support in a ib_sge
length field, which is usually 2G.

Will fix this in v2.
