When the tx_queue is started, previous stats are reset.
For tpa_v2 and P7, extended stats structure is used:
`struct bnxt_ring_stats_ext`, so passing wrong size to memset
makes not all stats to be reset. This commit sets correct size of
the structure passed to memset when zeroing-out previous stats.
