dw_dmac: Calling dwc_scan_descriptors from dwc_tx_status() after taking lock

Lock must be taken before calling dwc_scan_descriptors, as this may
access/modify shared data and queues. dwc_tx_status wasn't taking lock before
calling this routine. This patch add code that takes lock before calling
dwc_scan_descriptors.
