usb: gadget: udc: renesas_usb3: fix free size in renesas_usb3_dma_free_prd()
The commit 2d4aa21a73ba ("usb: gadget: udc: renesas_usb3: add support
for dedicated DMAC") has a bug in the renesas_usb3_dma_free_prd().
The size of dma_free_coherent() should be the same with dma_alloc_coherent()
Otherwise, this code causes a WARNING by mm/page_alloc.c when
renesas_usb3_dma_free_prd() is called. So, this patch fixes it.
