bonding: Fix negative jump label count on nested bonding
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: 9e2ee5c7e7c3 ("net, bonding: Add XDP support to the bonding driver")
