media: radio-keene: fix memory leak in error path
Fix a memory leak in usb_keene_probe(). The v4l2 control handler is
initialized and controls are added, but if v4l2_device_register() or
video_register_device() fails afterward, the handler was never freed,
leaking memory.
Add v4l2_ctrl_handler_free() call in the err_v4l2 error path to ensure
the control handler is properly freed for all error paths after it is
initialized.
Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
