[PATCH 1/3] scsi: ufs: retry link startup if that fails and device state is not active

[DooHyun Hwang]

Remove unnecessary link startup command if it was completed.

UniPro stack is reset and enabled when ufshc is enabled.
The link startup command is issued after enabling ufshc,
if link startup is completed, there is no needed to issue again.
