i2c: i2c-mux-gpio: remove error messages for probe deferrals
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 removes the error messages for these deferral cases.
