net/mlx5: Lag, record inactive state of bond device

A bond device will drop duplicate packets (received on inactive ports)
by default. A flag (all_slaves_active) can be set to override such
behaviour. This flag is a global flag per bond device (ALB mode isn't
supported by mlx5 driver so it can be ignored)

When NETDEV_CHANGEUPPER / NETDEV_CHANGEINFODATA event is received check if
there is an interface that is inactive.

Downstream patch will use this information in order to decide if a drop
rule is needed.
