[ Upstream commit 93e0401e0fc0c54b0ac05b687cd135c2ac38187c ]
The call to phy_stop() races with the later call to phy_disconnect(),
resulting in concurrent phy_suspend() calls being run from different
CPUs. The final call to phy_disconnect() ensures that the PHY is
stopped and suspended, too.
Fixes: c96e731c93ff ("net: bcmgenet: connect and disconnect from the PHY state machine")
