gpu: nvgpu: tsg: release default nvs domain ref

Browse Source 
A reference to the default scheduling domain is taken when a TSG is
opened. Although the explicit bind is designed to support only one bind,
the TSG is bound to the default one implicitly at that point. Release
the reference to avoid leaking it.

The domain might be null at that point if the default domain has been
removed; in that case there's just no domain to put back.
