usb: gadget: aspeed_udc: cleanup loop in ast_dma_descriptor_setup()
The "chunk >= 0" condition does not work because count is a u32. Also, really we shouldn't enter the loop when "chunk" is zero. Once that condition is fixed then there is no need for the "last" variable. I reversed the "if (chunk <= ep->chunk_max)" as well. The new loop is much simpler.
