[dpdk-stable] [PATCH] net/sfc: fix getting accumulative SW xstat

[Andrew Rybchenko]

From: Ivan Ilchenko <ivan.ilchenko at oktetlabs.ru>

Add missing initialisation of the accumulative SW xstat to
zero since it is sum of per-queue xstats.

Fixes: fdd7719eb3c ("net/sfc: add xstats for Rx/Tx doorbells")
