Input: synaptics - don't complain about failed resets

On many laptops (Compaq, HP) the touchpad is so slow responding
to reset that keyboard controller times out. The device is reset
nonetheless and works fine. Kill the "synaptics reset failed"
error; if device is not working then other parts of
synaptics_query_hardware() will fail anyway.
