tg3: Fix race condition in tg3_get_stats64().
[ Upstream commit f5992b72ebe0dde488fa8f706b887194020c66fc ]
The driver's ndo_get_stats64() method is not always called under RTNL.
So it can race with driver close or ethtool reconfigurations. Fix the
race condition by taking tp->lock spinlock in tg3_free_consistent()
when freeing the tp->hw_stats memory block. tg3_get_stats64() is
already taking tp->lock.
