usb: renesas_usbhs: fix the condition of is_done in usbhsf_dma_push_done
This patch fixes the condition of is_done in usbhsf_dma_push_done().
This function will be called after a transmission finished by DMAC.
So, the function should check if the transmission packet is short packet
or not. Also the function should call try_run to send the zero packet
by the pio handler if the "*is_done" is not set. Otherwize, the
transaction will not finish if a gadget driver sets the "zero" flag
in a transmission.
