Fix handling of aborted SCSI transfers on sam3u
Fix handling of aborted SCSI transfers on sam3u

If a SCSI transfer is aborted on the atsam3u via a MSC_REQUEST_RESET
then there is a chance the device will incorrectly detect an error and
start stalling on the MSD endpoints.  This patch fixes that problem by
changing the order in which endpoint 0 data is processed.
