When the transport is busy and we're sending an EH command drivers occasionally return 'BUSY'. As this in most cases is the TUR command sent as part of the error recovery this is a sure way to make the error recovery escalate. Returning 'NEEDS_RETRY' here will just retry the TUR command and eventually abort the original command, thus making error handling far smoother.
