Subject: [PATCH v4 1/8] scsi: ufs: Fix ufshcd_probe_hba() reture value in case ufshcd_scsi_add_wlus() fails

From: Bean Huo <beanhuo@...ron.com>

A non-zero error value likely being returned by ufshcd_scsi_add_wlus()
in case of failure of adding the WLs, but ufshcd_probe_hba() doesn't
use this value, and doesn't report this failure to upper caller.
This patch is to fix this issue.
