net: thunderx: Fix for multiqset not configured upon interface toggle

[ Upstream commit 6a9bab79bb79bd9b2eda16f0aba1b4c43f677be9 ]

When a interface is assigned morethan 8 queues and the logical interface
is toggled i.e down & up, additional queues or qsets are not initialized
as secondary qset count is being set to zero while tearing down.
