media: ov2659: Fix memory leaks in ov2659_probe()
commit 76142b137b968d47b35cdd8d1dc924677d319c8b upstream.
ov2659_probe() doesn't properly free control handler resources in failure
paths, causing memory leaks. Add v4l2_ctrl_handler_free() to prevent these
memory leaks and reorder the ctrl_handler assignment for better code flow.
Fixes: c4c0283ab3cd ("[media] media: i2c: add support for omnivision's ov2659 sensor")
