If a queue was canceled, then the buf_finish op was never called for the
pending buffers. So add this call to queue_cancel. Before calling buf_finish
set the buffer state to PREPARED, which is the correct state. That way the
states DONE and ERROR will only be seen in buf_finish if streaming is in
progress.
Since buf_finish can now be called from non-streaming state we need to
adapt the handful of drivers that actually need to know this.

The buf_finish op should always work, so change the return type to void.
Update the few drivers that use it.

The timestamp_type field used to contain only the timestamp type. Soon it
will be used for timestamp source flags as well. Rename the field
accordingly.
[m.chehab@samsung.com: do the change also to drivers/staging/media and at s2255]

bw-qcam didn't set the timestamp and it didn't set q->timestamp_type.

I know, nobody really cares about this black-and-white webcam anymore, but
it was fun to do.

We should keep just the I2C drivers under drivers/media/video, and
then rename it to drivers/media/i2c.
