usb: gadget: aspeed_udc: fix handling of tx_len == 0
The bug is that we should still enter this loop if "tx_len" is zero.
After adding the "last" variable, then the "chunk >= 0" condition is no
longer required but I left it for readability.
Fixes: c09b1f372e74 ("usb: gadget: aspeed_udc: cleanup loop in ast_dma_descriptor_setup()")
