net: dsa: introduce bridge notifier
A slave device will now notify the switch fabric once its port is bridged or unbridged, instead of calling directly its switch operations. This code allows propagating cross-chip bridging events in the fabric. Signed-off-by: Vivien Didelot <vivien.didelot@savoirfairelinux.com> Signed-off-by: David S. Miller <davem@davemloft.net>

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.
