From: Vladimir Oltean <vladimir.oltean@nxp.com>

Now that br_switchdev_set_port_flag is never called from under br->lock,
it runs in sleepable context.

All switchdev drivers handle SWITCHDEV_PORT_ATTR_SET as both blocking
and atomic, so no changes are needed on that front.

Changes in v2:
Patch is new.
