gallium/cso: fix sampler / sampler_view counts

Browse Source 
Now that it is possible to query drivers for the max sampler view it should
be safe to increase this without crashing.
Not entirely convinced this really works correctly though if state trackers
using non-linked sampler / sampler_views use this.
