In case a client fails to connect in mei_cldev_enable(), the
caller won't call the mei_cldev_disable leaving the client
in a linked stated. Upon driver unload the client structure
will be freed in mei_cl_bus_dev_release(), leaving a stale pointer
on a fail_list. This will eventually end up in crash
during power down flow in mei_cl_set_disonnected().
