Shiraz Saleem c4eb44ffd9 RDMA/irdma: Check return value from ib_umem_find_best_pgsz 
iwmr->page_size stores the return from ib_umem_find_best_pgsz and maybe
zero when used in ib_umem_num_dma_blocks thus causing a divide by zero
error.

Fix this by erroring out of irdma_reg_user when 0 is returned from
ib_umem_find_best_pgsz.
