Slawomir Laba 974578017f iavf: Add waiting so the port is initialized in remove 
There exist races when port is being configured and remove is
triggered.

unregister_netdev is not and can't be called under crit_lock
mutex since it is calling ndo_stop -> iavf_close which requires
this lock. Depending on init state the netdev could be still
unregistered so unregister_netdev never cleans up, when shortly
after that the device could become registered.

Make iavf_remove wait until port finishes initialization.
All critical state changes are atomic (under crit_lock).
Crashes that come from iavf_reset_interrupt_capability and
iavf_free_traffic_irqs should now be solved in a graceful
manner.

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.
