[PATCH] net/ice: fix statistics

[Mingjin Ye]

When the stats_get api is called for the first time in pmd, the offset
of the stats register is not recorded. That results in all the obtained
count values being 0.

This patch adds reset statistics before dev_init returning. That avoids
some noise being counted.
