ttusb2: Don't use stack variables for DMA

commit ff17999184ed13829bc14c3be412d980173dff40 upstream.

The ttusb2_msg function uses on-stack variables to submit commands to
dvb_usb_generic.  This eventually gets to the DMA api layer and will throw a
traceback if the debugging options are set.

This allocates the temporary buffer variables with kzalloc instead.
