usb: gadget: pch_udc: Check for DMA mapping error
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]
Fixes: abab0c67c061 ("usb: pch_udc: Fixed issue which does not work with g_serial")
