scsi: ufs: core: Complain if UIC argument 2 is invalid

Browse source

According to the UFSHCI standard, the lowest byte of UIC argument 2 is
an output value. Additionally, ufshcd_uic_cmd_compl() is based on the
assumption that the lowest byte of UIC argument 2 is zero. Hence,
complain if the result byte is set when a UIC command is submitted.
