===================
cls_bpf: fix offload state tracking with block callbacks

After introduction of block callbacks classifiers can no longer track
offload state.  cls_bpf used to do that in an attempt to move common
code from drivers to the core.  Remove that functionality and fix
drivers.

The user-visible bug this is fixing is that trying to offload a second
filter would trigger a spurious DESTROY and in turn disable the already
installed one.
