kernel-driver-development-debugging: adjust explanation about dynamic debug
Some people where confused about the behavior of
DEBUG/CONFIG_DYNAMIC_DEBUG: it wasn't clear to them that it's only
when neither DEBUG nor CONFIG_DYNAMIC_DEBUG are used that the messages
are not compiled in. I.e, they thought they needed both the debugging
messages to be enabled.
Let's reword a bit the explanation in an attempt to clarify that.

\item Very powerful feature to only get the debug messages you're
interested in.
\end{itemize}
- \item When \code{DEBUG} is not defined and
- \code{CONFIG_DYNAMIC_DEBUG} is not enabled, these messages are not
- compiled in.
