This works for the URBs allocated with usb_alloc_urb(), as those are allocated from cohernent DMA pools, but the flag was also added for the VBI and audio URBs, which have a manually allocated area. This leaves the random trash in the structure after allocation as the DMA address, corrupting memory and preventing VBI and audio from working. Letting the USB core map the buffers solves the problem.

Since this driver has been merged at the same time as the core changes it doesn't set this flags and thus its all file operations except IOCTL are not properly serialized. Fix this by adding file ops locking in the driver.
