Revert "anv: limit URB reconfigurations when using blorp"
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 0d46e404677264bfb12ada15290e39c10a5eb455
since it didn't seem to yield any performance improvement.
