scsi: ufs: core: Fix hba->last_dme_cmd_tstamp timestamp updating logic
The ufshcd_add_delay_before_dme_cmd() always introduces a delay of
MIN_DELAY_BEFORE_DME_CMDS_US between DME commands even when it's not
required. The delay is added when the UFS host controller supplies the
quirk UFSHCD_QUIRK_DELAY_BEFORE_DME_CMDS.
Fix the logic to update hba->last_dme_cmd_tstamp to ensure subsequent DME
commands have the correct delay in the range of 0 to
MIN_DELAY_BEFORE_DME_CMDS_US.
Update the timestamp at the end of the function to ensure it captures the
latest time after any necessary delay has been applied.
