Currently in case of error caused by bio_pc_add_page in pblk_bio_add_pages two issues occur when calling from pblk_rb_read_to_bio(). First one is in pblk_bio_free_pages, since we are trying to free pages not allocated from our mempool. Second one is the warn from dma_pool_free, that we are trying to free NULL pointer dma. This commit fix both issues.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
