This driver always uses a DMA array made up of PAGE_SIZE elements, so just use ib_umem_num_dma_blocks(). Since rdma_for_each_dma_block() always iterates exactly ib_umem_num_dma_blocks() there is no need for the early exit check in build_user_pbes(), delete it.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
