usb: renesas_usbhs: disable TX IRQ before starting TX DMAC transfer
commit 6490865c67825277b29638e839850882600b48ec upstream.
This patch adds a code to surely disable TX IRQ of the pipe before
starting TX DMAC transfer. Otherwise, a lot of unnecessary TX IRQs
may happen in rare cases when DMAC is used.
