Subject: [PATCH iwl-net v3] ice: Block PF reinit if attached to bond

PF interface part of LAG should not allow driver reinit via devlink. The
Bond config will be lost due to driver reinit. ice_devlink_reload_down is
called before PF driver reinit. If PF is attached to bond,
ice_devlink_reload_down returns error.

Fixes: trailer
