nfp: flower: support offloading multiple rules with same cookie
When multiple netdevs are attached to a tc offload block and register for
callbacks, a rule added to the block will be propogated to all netdevs.
Previously these were detected as duplicates (based on cookie) and
rejected. Modify the rule nfp lookup function to optionally include an
ingress netdev and a host context along with the cookie value when
searching for a rule. When a new rule is passed to the driver, the netdev
the rule is to be attached to is considered when searching for dublicates.
When a stats update is received from HW, the host context is used
alongside the cookie to map to the correct host rule.
