[PATCH] i2c: i2c-mux-gpio: Change log level to debug for probe deferrals

[Ioan Nicu]

Probe deferral is not an error case. It happens only when
the necessary dependencies are not there yet.

The driver core is already printing a message when a driver
requests probe deferral, so this can be traced in the logs
without these error prints.

This patch changes the error messages from these deferral cases
to debug messages.
