From: Bean Huo <beanhuo@micron.com> commit b9fc5320212efdfb4e08b825aaa007815fd11d16 upstream. 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.
