net/mlx5: fix port initialization of switch domain

All active ports that belong to the same E-switch share domain_id
value.
Port initialization procedure searches through a database for existing
port with matching properties. New domain_id allocated if match was
not located. Otherwise, new port inherits existing domain_id.

Port initialization did not pass enough info to search procedure to
find existing matches. Therefore, each port was created with a private
domain_id value. As the result, port_id flow action failed because it
could not match ports in a rule to E-switch.

The patch adds dpdk_dev with port properties to device search.
