bridge: Fix qos_unixctl_show bug.
netdev_get_qos returns a value to indicate if an error has occurred while attempting to query the QoS configuration of an interface. If an error does occur the pointer argument passed to it will be set to null before returning. Currently the vswitch will segfault if this occurs as qos_unixctl_show will attempt to access the pointer directly after it calls netdev_get_qos. Avoid this by adding a check for the return value and flagging an appropriate error message to appctl.
