Today if a mux i2c bus gets created the default retry count of the
muxed bus is zero. Hence it it possible that you end up with a
situation where the parent controller sets a default retry count
which gets applied and used while the muxed bus (using the same
controller) has a default retry count of zero. This can be solved
by initializing the retry count of the muxed bus by the retry count
of the parent at creation time.
