Merge branch 'ocelot-vcap-fixes'

Vladimir Oltean says:

====================
Ocelot VCAP fixes

Changes in v2:
fix the NPDs and UAFs caused by filter->trap_list in a more robust way
that actually does not introduce bugs of its own (1/5)

This series fixes issues found while running
tools/testing/selftests/net/forwarding/tc_actions.sh on the ocelot
switch:

- NULL pointer dereference when failing to offload a filter
- NULL pointer dereference after deleting a trap
- filters still having effect after being deleted
- dropped packets still being seen by software
- statistics counters showing double the amount of hits
- statistics counters showing inexistent hits
- invalid configurations not rejected
====================
