usb: renesas_usbhs: tidyup usbhs_for_each_dfifo macro

Browse Source 
Current usbhs_for_each_dfifo macro will read out-of-array's
memory after last loop operation.
It was not good C language operation, and the binary which was
compiled by (at least) gcc 4.8.1 is broken.

This patch is based on

(usb: renesas_usbhs: tidyup original usbhsx_for_each_xxx macro)
