net: cpsw: fix NULL pointer exception in the probe error path
In certain cases when the probe function fails the error path calls cpsw_remove_dt() before calling platform_set_drvdata(). This is an issue as cpsw_remove_dt() uses platform_get_drvdata() to retrieve the cpsw_common data and leds to a NULL pointer exception. This patches fixes it by calling platform_set_drvdata() earlier in the probe.
