cso: don't release sampler states that are bound
This fixes random radeonsi GPU hangs in Batman Arkham: Origins (Wine) and
probably many other games too.
cso_cache deletes sampler states when the cache size is too big and doesn't
check which sampler states are bound, causing use-after-free in drivers.
Because of that, radeonsi uploaded garbage sampler states and the hardware
went bananas. Other drivers may have experienced similar issues.
