net/bnxt: fix port default rule create/destroy

Currently, the flow_ids of port_to_app/app_to_port & tx_cfa_action
for the first port are getting over-written by the second port because
these fields are stored in the ulp context which is common across the
ports.

This patch fixes the problem by having per port structure to store these
fields.
