GPU crashes on OSL param tweak

Arnold GPU crashes when tweaking OSL parameters.

Here you'll find a dummy OSL shader, info and a Maya scene.
Just tweak some parameters and Arnold GPU (optix backend) will crash.

I also see errors while changing parameters:

// Error: ERROR   |    [gpu] OptiX call failed: (7001) OPTIX_ERROR_INVALID_VALUE
// Error: ERROR   |    [gpu] Exception thrown during GPU execution: OPTIX_ERROR_INVALID_VALUE

Hopefully you marked this as 'outstanding' or 'showstopper'.
