With nested bonding devices the nested bond device's ndo_bpf was
called without a program causing it to decrement the static key
without a prior increment leading to negative count.
Fix the issue by 1) only calling slave's ndo_bpf when there's a
program to be loaded and 2) only decrement the count when a program
is unloaded.
Fixes: 9e2ee5c7e7 ("net, bonding: Add XDP support to the bonding driver")

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.
