usb: renesas_usbhs: missed the "running" flag in usb_dmac with rx path
This fixes an issue that a gadget driver (usb_f_fs) is possible to
stop rx transactions after the usb-dmac is used because the following
functions missed to set/check the "running" flag.
- usbhsf_dma_prepare_pop_with_usb_dmac()
- usbhsf_dma_pop_done_with_usb_dmac()
So, if next transaction uses pio, the usbhsf_prepare_pop() can not
start the transaction because the "running" flag is 0.
