Revert "anv: limit URB reconfigurations when using blorp"

Browse Source 
In commit 0d46e404 ("anv: limit URB reconfigurations when using
blorp") we tried to limit the number of URB reconfiguration by
checking if the last allocation is large enough to fit the blorp
dispatch.

We used the last bound pipeline to compare the allocation. The problem
with this is that the pipeline is bound but its commands might not
have been emitted into the command buffer yet.

Let's just revert commit 0d46e40467
since it didn't seem to yield any performance improvement.
