usb: image: microtek: stop SG processing after transfer errors
When an SG URB completes with an error, mts_do_sg() calls mts_transfer_cleanup(), which completes the SCSI command through scsi_done(). However, the callback continues advancing the scatterlist and may submit another URB for a command that has already been completed. Return immediately after the cleanup so that no further processing is performed on the completed command.
