USB: fsl_qe_udc: Fix oops on QE UDC probe failure
In case of probing errors the driver kfrees the udc_controller, but it
doesn't set the pointer to NULL.
When usb_gadget_register_driver is called, it checks for udc_controller
!= NULL, the check passes and the driver accesses nonexistent memory.
Fix this by setting udc_controller to NULL in case of errors.
While at it, also implement irq_of_parse_and_map()'s failure and cleanup
cases.
