[CUDA] Use the multi-element remove function in EraseUnwantedCUDAMatches.

Summary:
Bug pointed out by Benjamin Kramer in r264008.  I think the bug is
benign because by the time this is called, we should only have at most
two overloads to consider (either a host and a device overload, or a
host+device overload, but not all three).
