net: thunderx: Fix receive packet stats
Counting rx packets for every CQE_RX in CQ irq handler is incorrect.
Synchronization is missing when multiple queues are receiving packets
simultaneously. Like transmit packet stats use HW stats here.
Also removed unused 'cqe_type' parameter in nicvf_rcv_

net: thunderx: Fix for HW TSO not enabled for secondary qsets
For secondary Qsets 'hw_tso' is not getting set as probe() returns
much earlier. Fixed it by moving silicon revision check.

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