mdev->state device state is not protected by the QP for which WRs are
being processed. Therefore, there is no need to hold spin lock while
checking mdev state.
Given that device fatal error is unlikely situation, wrap the condition
check with unlikely().
Additionally, kernel QP1 is also a kernel ULP for which soft CQEs needs
to be generated. Therefore, check for device fatal error before
processing QP1 work requests.

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.
