To: davem; +Cc: netdev, Stephen Hemminger
The network device operation for reading statistics is only called
in one place, and it ignores the return value. Having a structure
return value is potentially confusing because some future driver could
incorrectly assume that the return value was used.
Fix all drivers with ndo_get_stats64 to have a void function.

In dev_get_stats() the statistic structure storage has already been
zeroed. Therefore network drivers do not need to call memset() again.
