net/hns3: fix Rx/Tx errors stats

Abnormal errors stats in Rx/Tx datapath are statistics
items in driver, and displayed in xstats. They should
be cleared by the rte_eth_xstats_reset api, instead of
the rte_eth_stats_reset.

Fixes: c4b7d6761d01 ("net/hns3: get Tx abnormal errors in xstats")
Fixes: 521ab3e93361 ("net/hns3: add simple Rx path")
Fixes: bba636698316 ("net/hns3: support Rx/Tx and related operations")
