net: thunderx: Fix receive packet stats

[ Upstream commit ad2ecebd67d8a80fe5412d11df375a5ed2db7cd1 ]

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_pkt_handler().
