nfp: flower: fix ingress police using matchall filter

Referenced commit introduced nfp_policer_validate in the progress
installing rate limiter. This validate check the action id and will
reject police with CONTINUE, which is required to support ingress
police offload.

Fix this issue by allowing FLOW_ACTION_CONTINUE as notexceed action
id in nfp_policer_validate

Fixes: d97b4b105ce7 ("flow_offload: reject offload for all drivers with invalid police parameters")
