etnaviv: fix texture barrier implementation

Browse source 
The current implementation has a number of issues:
- it doesn't flush the depth cache, even though this can also be changed
  due to fragment shader operations and thus is included in the definition
  of glTextureBarrier
- it doesn't flush the vertex sampler cache
- it doesn't stall the pipeline until the flushes are done

Fix those issues and drop the comment, as it's pretty clear from the
code what is being done.
