net: dsa: mv88e6xxx: get STU entry on VTU GetNext
Now that the code reads both VTU and STU data on VTU GetNext operation,
fetch the STU entry data of a VTU entry at the same time.
The STU data bits are masked with the VTU data bits and they are now all
read at the same time a VTU GetNext operation is issued.
