[Mesa-dev] [PATCH] i965/miptree: Set supports_fast_clear = false in make_shareable

[Jason Ekstrand]

The make_shareable function deletes the aux buffer and then whacks
aux_usage to ISL_AUX_USAGE_NONE but not unsetting supports_fast_clear.
Since we only look at supports_fast_clear to decide whether or not to do
fast clears, this was causing assertion failures.
