[ Upstream commit 62c8a069b510d905039abd4097434f190a316941 ]
Marvell PPv2 Header Parser sets some bits in the 'result_info' field in
each lookup iteration, to identify different packet attributes such as
DSA / VLAN tag, protocol infos, etc. This is used in further
classification stages in the controller.
It's the DSA tag detection entry that is in charge of detecting when there
is a single VLAN tag.
This commits adds the missing update of the result_info in this case.
