usb: gadget: pch_udc: Check for DMA mapping error
[ Upstream commit 4a28d77e359009b846951b06f7c0d8eec8dce298 ]
DMA mapping might fail, we have to check it with dma_mapping_error().
Otherwise DMA-API is not happy:
DMA-API: pch_udc 0000:02:02.4: device driver failed to check map error[device address=0x00000000027ee678] [size=64 bytes] [mapped as single]
