net-forcedeth: fix possible stats inaccuracies on 32b hosts
The software stats are updated from BH, this change ensures that 32b
UP hosts use appropriate protection.
Tested:
- HW/SW stats consistent with pktgen (in particular tx=rx)
- HW/SW stats consistent when tx/rx offloads disabled
- no problem with+without lockdep (SMP 16-way)
