ethtool: stats: Use struct_group() to clear all stats at once
In preparation for FORTIFY_SOURCE performing compile-time and run-time field bounds checking for memset(), avoid intentionally writing across neighboring fields. Add struct_group() to mark region of struct stats_reply_data that should be initialized, which can now be done in a single memset() call.
