octeontx2-pf: qos: fix VF root node parent queue index

[ Upstream commit b7db94734e785e380b0db0f9295e07024f4d42a0 ]

The current code configures the Physical Function (PF) root node at TL1
and the Virtual Function (VF) root node at TL2.

This ensure at any given point of time PF traffic gets more priority.

                    PF root node
                      TL1
                     /  \
                    TL2  TL2 VF root node
                    /     \
                   TL3    TL3
                   /       \
                  TL4      TL4
                  /         \
                 SMQ        SMQ

Due to a bug in the current code, the TL2 parent queue index on the
VF interface is not being configured, leading to 'SMQ Flush' errors
