Callback unbinding needs to be done after nf_flow_table_free(),
otherwise entries are not removed from the hardware.
Update nft_unregister_flowtable_net_hooks() to call
nf_unregister_net_hook() instead since the commit/abort paths do not
deal with the callback unbinding anymore.
Add a comment to nft_flowtable_event() to clarify that
flow_offload_netdev_event() already removes the entries before the
callback unbinding.

Fixes ff4bf2f42a40 ("netfilter: nf_tables: add nft_unregister_flowtable_hook()")

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.
