usb: use usb_serial_put in usb_serial_probe errors
commit 0658a3366db7e27fa32c12e886230bb58c414c92 upstream.
The use of kfree(serial) in error cases of usb_serial_probe
was invalid - usb_serial structure allocated in create_serial()
gets reference of usb_device that needs to be put, so we need
to use usb_serial_put() instead of simple kfree().
