This patch corrects two oversights relating to releasing resources
and DCB initialisation.
1. If mapping of the dcbcfg_tbl area fails: an error should be
propagated, allowing partial initialisation (probe) to be unwound.
2. Conversely, if where dcbcfg_tbl is successfully mapped: it should
be unmapped in nfp_nic_dcb_clean() which is called via various error
cleanup paths, and shutdown or removal of the PCIE device.

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.
