Applied with updated commit message:

    gpudev: manage null parameters in memory functions
    
    The gpudev functions free, register and unregister
    return gracefully if input pointer is NULL or size 0,
    as API doc was indicating no-op accepted values.
    
    CUDA driver checks are removed because redundant
    with the checks added in gpudev library.
