etnaviv: allow sampler TS even if the resource is flushed

Browse source 
As long as the TS is valid we can use the tile status to optimize the
sample fetch, even if the resource has been flushed for any reason.
Do the check for valid TS first when checking whether to enable sampler
TS to avoid all the other checks when TS isn't usable.
