net: xfrm: use core API for updating/providing stats
Commit d3fd65484c781 ("net: core: add dev_sw_netstats_tx_add") has added function "dev_sw_netstats_tx_add()" to update net device per-cpu TX stats. Use this function instead of own code. While on it, remove xfrmi_get_stats64() and replace it with dev_get_tstats64().
