turnip: Unconditionaly remove descriptor set from pool's list on free

We didn't remove desc set from the pool's list if pool was
host_memory_base. On the other hand in there is no point in removing
desc set from the list in DestroyDescriptorPool/ResetDescriptorPool.

Fixes: da7a4751
("turnip: Drop references to layout of all sets on pool reset/destruction")

Fixes cts tests:
 dEQP-VK.api.buffer_marker.graphics.default_mem.bottom_of_pipe.memory_dep.draw
 dEQP-VK.api.buffer_marker.graphics.default_mem.bottom_of_pipe.memory_dep.dispatch
