V4L/DVB: videobuf: prepare to make locking optional in videobuf
Currently videobuf uses the vb_lock mutex to lock its data structures.
But this locking will (optionally) move into the v4l2 core, which means
that in that case vb_lock shouldn't be used since the external lock is already
held.
Prepare for this by adding a pointer to such an external mutex and
don't lock if that pointer is set.
