In iwl_pcie_ctxt_info_gen3_init there are cases that the allocated dma
memory is leaked in case of error.
DMA memories prph_scratch, prph_info, and ctxt_info_gen3 are allocated
and initialized to be later assigned to trans_pcie. But in any error case
before such assignment the allocated memories should be released.
First of such error cases happens when iwl_pcie_init_fw_sec fails.
Current implementation correctly releases prph_scratch. But in two
sunsequent error cases where dma_alloc_coherent may fail, such
releases are missing.
This commit adds release for prph_scratch when allocation for
prph_info fails, and adds releases for prph_scratch and prph_info when
allocation for ctxt_info_gen3 fails.

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.
