i965: Remove unneeded VS workaround stalls on Baytrail.
According to the workarounds list, these stalls aren't needed on
production Baytrail systems. Piglit confirms that as well.
These cause a small slowdown when we are sending a large number of small
batches to the GPU. Removing these improves performance by up to 5% on
some CPU bound SynMark tests (Batch[4-7], DrvState1, HdrBloom,
Multithread, ShMapPcf).
