common/sfc_efx/base: support recirculation ID in outer rules

Browse Source 
When an outer rule is hit, it can pass recirculation ID down
to action rule lookup, and action rules can match on this ID
instead of matching on the outer rule allocation handle.
By default, recirculation ID is assumed to be zero.

Add an API to set recirculation ID in outer rules.
