[media] cx18: Move spinlock and vb_type initialisation into stream_init

Browse Source 
The initialisation of vb_type in serialized_open was preventing
REQBUFS from working reliably. Remove it, and move the spinlock into
stream_init for good measure - it's only used when we have a stream
that supports videobuf anyway.
