Subject: usb: typec: ucsi: Acknowledge the GET_ERROR_STATUS command completion

We found PPM will not send any notification after it report error status and OPM issue GET_ERROR_STATUS command to read the details about error.

According UCSI spec, PPM may clear the Error Status Data after the OPM has acknowledged the command completion.

This change add operation to acknowledge the command completion from PPM.
