media: docs-rst: media: Document broken frame handling in stream stop for CSI-2

Some CSI-2 transmitters will finish an ongoing frame whereas others will
not. Document that receiver drivers should not assume a particular
behaviour but to work in both cases.

Stopping the transmitter
^^^^^^^^^^^^^^^^^^^^^^^^
A transmitter stops sending the stream of images as a result of
calling the ``.s_stream()`` callback. Some transmitters may stop the
stream at a frame boundary whereas others stop immediately,
effectively leaving the current frame unfinished. The receiver driver
should not make assumptions either way, but function properly in both
cases.
