highmem region, the usb_sg_init() in the core/message.c will leave
transfer_buffer to NULL if the sg_buf is in highmem, but in the
dwc_otg driver, it returns -EINVAL unconditionally if transfer_buffer
is NULL.

The driver can handle the situation of buffer to be NULL, if it is in
DMA mode, it will convert an address from transfer_dma.

But if the conversion fails or it is in the PIO mode, we should check
buffer and return -EINVAL if it is NULL.
