As part of the commitb148bb238c("bnxt_en: Fix possible crash in bnxt_fw_reset_task()."), cancel_delayed_work_sync() is called only for VFs to fix a possible crash by cancelling any pending delayed work items. It was assumed by mistake that the flush_workqueue() call on the PF would flush delayed work items as well. As flush_workqueue() does not cancel the delayed workqueue, extend the fix for PFs. This fix will avoid the system crash, if there are any pending delayed work items in fw_reset_task() during driver's .remove() call. Unify the workqueue cleanup logic for both PF and VF by calling cancel_work_sync() and cancel_delayed_work_sync() directly in bnxt_remove_one().

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.
