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().
