Shaurya Rane 7fa9754f48 media: radio-keene: fix memory leak in error path ...

[ Upstream commit b8bf939d77 ]

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.
