[ Upstream commit b9fc5320212efdfb4e08b825aaa007815fd11d16 ]
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.
Fixes: 2a8fa600445c ("ufs: manually add well known logical units")
