V4L/DVB (6060): ivtv: fix IVTV_IOC_DMA_FRAME bug introduced by highmem bugfix
The return value of ivtv_udma_fill_sg_list() was changed by the highmem bugfix, but that return value was still used in ivtv-yuv.c. Revert to the old return value, but in addition return -1 in case of a memory allocation error.
