[ Upstream commita8417330f8] Fix a deadlock introduced by commit974578017f("iavf: Add waiting so the port is initialized in remove") due to race condition between iavf_shutdown and iavf_remove, where iavf_remove stucks forever in while loop since iavf_shutdown already set __IAVF_REMOVE adapter state. Fix this by checking if the __IAVF_IN_REMOVE_TASK has already been set and return if so.

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.
