Yihang Li f58c897006 scsi: hisi_sas: Set a port invalid only if there are no devices attached when refreshing port id
Currently the driver sets the port invalid if one phy in the port is not
enabled, which may cause issues in expander situation. In directly attached
situation, if phy up doesn't occur in time when refreshing port id, the
port is incorrectly set to invalid which will also cause disk lost.

Therefore set a port invalid only if there are no devices attached to the
port.
