V4L/DVB (11142): au0828: fix oops on ARM platform when allocating transfer buffers
Add missing URB_NO_TRANSFER_DMA_MAP flag, since the use of consistent memory
is not permitted for DMA on the ARM platform.
Thanks to Paul Thomas <pthomas8589@gmail.com> for providing sample ARM
hardware that was experiencing the oops (tested on the at91rm9200 based
LinuxStamp).
Thanks to David Brownell <david-b@pacbell.net> for providing insight into the
ARM memory architecture.
