fsl_usb2_udc: Fix oops on probe failure.

In some circumstances when fsl_udc_probe fails udc_controller is freed but
the pointer remains non-NULL. fsl_udc_remove will then try and teardown
the partly initialized and freed controller structure resulting in an oops.
This patch ensures udc_controller is either NULL or fully initialized after
fsl_udc_probe.
