igb: fix stats handling
There are currently some problems with igb.
- On 32bit arches, maintaining 64bit counters without proper
synchronization between writers and readers.
- Stats updated every two seconds, as reported by Jesper.
(Jesper provided a patch for this)
- Potential problem between worker thread and ethtool -S
This patch uses u64_stats_sync, and convert everything to be 64bit safe,
SMP safe, even on 32bit arches. It integrates Jesper idea of providing
accurate stats at the time user reads them.
