Julian Wiedmann 8b2cdc004d net/smc: remove device from smcd_dev_list after failed device_add() 
[ Upstream commit 444d7be9532dcfda8e0385226c862fd7e986f607 ]

If the device_add() for a smcd_dev fails, there's no cleanup step that
rolls back the earlier list_add(). The device subsequently gets freed,
and we end up with a corrupted list.

Add some error handling that removes the device from the list.
