Subject: [PATCH] scsi: ufs: Don't spew log for enabling WB in ufshcd_wb_config()

From: Yue Hu <huyue2@...ong.com>

Since ufshcd_wb_ctrl() will spew error/debug log firstly, no need to
spew similar error/info log again in the caller ufshcd_wb_config().

Also, several log words in ufshcd_wb_ctrl() are not consistent with
other sites, let's improve them. And remove unhelpful ret from debug
log due to successful control.
