camera_sensor: Suppress error message if test patterns are unavailable

If a sensor driver does not support test patterns (e.g. IMX477),
libcamera throws an unnecessary error message during initialisation when
it sets the test pattern to off.

Fix this by moving the error message into setTestPatternMode() where the
pipeline handler explicitly requests to set a test pattern.
