gallium/docs: clarify that samplers are not used with PIPE_BUFFER resources
Commit 8aba778fa2cd98a0b5a7429d3c5057778a0c808c "st/mesa: don't set sampler states for TBOs" changed how texture buffer objects are handled. Document the new convention. Reviewed-by: Roland Scheidegger <sroland@vmware.com>

+Samplers
+^^^^^^^^
+
+pipe_sampler_state objects control how textures are sampled (coordinate
+wrap modes, interpolation modes, etc). Note that samplers are not used
+for texture buffer objects. That is, pipe_context::bind_sampler_views()
+will not bind a sampler if the corresponding sampler view refers to a
+PIPE_BUFFER resource.
