Xin Long 16cf72bb08 team: call netdev_change_features out of team lock
Commit f6988cb63a ("team: don't call netdev_change_features under
team->lock") fixed the issue calling netdev_change_features under
team->lock for team_compute_features.

But there are still two places where it calls netdev_change_features
under team->lock, team_port_add and team_port_del. It may cause a
dead lock when the slave port with LRO enabled is added.

This patch is to fix this dead lock by moving netdev_change_features
out of team_port_add and team_port_del, and call it after unlocking
the team lock.
