V4L/DVB (7566): videobuf-dvb: allow its usage with videobuf-vmalloc
videobuf-dvb were still using a function that were videobuf-dma-sg dependent. This patch creates a generic handler for this function. This way, videobuf-dvb can now work with all videobuf implementations. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
