input: add valuator_mask_free() to free a valuator mask.

Expecting the caller to free the mask requires us to keep it in a single
memory block (which may be an issue lateron), aside from leaving the API
asymetrical. Provide valuator_mask_free() to free the memory and reset the
mask pointer to NULL.
