Gallium caches sampler states for TBOs. Now if a buffer is first
attached to a TBO specifying one format, and later attached by
specifying another format and this TBO is then used, that would lead
to an assertion failure in debug builds, or to invalid rendering in
release builds, because the TBO picks the original, wrong format for
the sampler view.
Resolve this by signalling the change to Gallium (and other drivers), so
that Gallium clears the sampler view cache.
