Fix memset() accessing out of range address when reply_queue count is less
than RDPQ_MAX_INDEX_IN_ONE_CHUNK (i.e. 16) in non-RDPQ mode.
In non-RDPQ mode, the driver allocates a single contiguous pool of size
reply_queue's count * reqly_post_free_sz. But the driver is always
memsetting this pool with size 16 * reqly_post_free_sz. If reply queue
count is less than 16 (i.e. when MSI-X vectors enabled < 16), the driver is
accessing out of range address and this results in 'BUG: unable to handle
kernel paging request at fff0x...x' bug.
Make driver use dma_pool_zalloc() API to allocate and zero the pool.

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.
