[gstv4l2sink] destroy open buffers when changing to NULL

In the case we change the State from READY_TO_NULL the open buffers
still hold a open dup filedescriptor to the device, therefore the device
release function will not be called and the device probably answer with
-EBUSY when we reopen it at transition NULL_TO_READY.
