scsi: ufshcd-qti: Keep the correct device and link state

If the device and link are marked as off, suspend routine wouldn't
turn-off the device and link.
But the regulators would be put to lpm mode.
However, the ufs device is still drawing active mode current.
Thus this leads to a OCP in PMIC.

Hence, don't mark the device and link as off in case of error,
if it doesn't reflect the correct state.
