Although it failed to encapsulate loop within nv50_sampler_state_delete effectively failing to clear the sampler state, apart from exadurating the illegal memory access issue. Fixes gcc warning "array subscript is above array bounds" and "Nesting level does not match indentation" and "Out-of-bounds read" defects reported by Coverity.
