be2net: Fix to avoid hardware workaround when not needed
[ Upstream commit 52fe29e4bb614367c108b717c6d7fe5953eb7af3 ]
Hardware workaround requesting hardware to skip vlan insertion is necessary
only when umc or qnq is enabled. Enabling this workaround in other scenarios
could cause controller to stall.
