Jacob Keller e62e51ccc8 iavf: check for removal state before IAVF_FLAG_PF_COMMS_FAILED 
[ Upstream commit 91896c8acc ]

In iavf_adminq_task(), if the function can't acquire the
adapter->crit_lock, it checks if the driver is removing. If so, it simply
exits without re-enabling the interrupt. This is done to ensure that the
task stops processing as soon as possible once the driver is being removed.

However, if the IAVF_FLAG_PF_COMMS_FAILED is set, the function checks this
before attempting to acquire the lock. In this case, the function exits
early and re-enables the interrupt. This will happen even if the driver is
already removing.

Avoid this, by moving the check to after the adapter->crit_lock is
acquired. This way, if the driver is removing, we will not re-enable the
interrupt.

README 

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.
