[Mesa-dev] [PATCH] mesa/st: reduce size of state->st bitmask

[Rob Clark]

In d035d50 this changed to 64b.. which I'm pretty sure was
unintentional.  Revert it back to 32b so the entire state struct
is a nice round 64b (cache-line size).

(Note sure that it would actually be measurable, but I did notice
that check_state() was hot in some benchmarks.)
