workaround or potential fix

We have a vulkan demo that is leaking dynamic state. This demo recently started
using a compute shader.

I don't have a reduced test case, but check out the attached workaround/fix.

Mesa branch 13.0.3

anv_pool_state_emit, which is used only from this one location, requires a
matching free.  Using the dynamic state stream instead prevents the leak
because the stream is cleaned up on finish.
