net: macb: Use net_device_stats from struct net_device
Instead of using a private copy of struct net_device_stats in struct macb, use stats from struct net_device. Cc: Nicolas Ferre <nicolas.ferre@atmel.com> Signed-off-by: Tobias Klauser <tklauser@distanz.ch>

However, conditions at the time of the race are count of PERCPU_COUNT_BIAS + 0 and __PERCPU_REF_DEAD and __PERCPU_REF_ATOMIC set. The fix is to make the tryget routines use an actual boolean internally instead of the atomic long result truncated to a int.
