When hitting the recirculation limit, the kernel would currently log
something like this:

[   58.586597] openvswitch: ovs-system: deferred action limit reached, drop 
recirc action

Which isn't all that useful to debug as we only have the interface name
to go on but can't track it down to a specific flow.

With this change, we now instead get:

[   58.586597] openvswitch: ovs-system: deferred action limit reached, drop 
recirc action (recirc_id=0x9e)

Which can now be correlated with the flow entries from OVS.
