Previously this check was skipped for pools with
VK_DESCRIPTOR_POOL_CREATE_FREE_DESCRIPTOR_SET_BIT unset, but after
96a240e1 we need to check this otherwise we risk overflowing
radv_descriptor_pool::entries into the host memory base
This fixes a crash to desktop when launching Dota 2, which overallocates
descriptor sets and expects an error to allocate another descriptor pool
Fixes: 96a240e176 ("radv: fix memory leak of descriptor set layout")
