pvr: Add missing NULL checks in some vkDestroy...() functions

Seems like `dEQP-VK.api.null_handle.destroy_device` was already
passing but let's add the null check in case of future changes
which might not accept NULL.

Fixes:
  dEQP-VK.api.null_handle.destroy_descriptor_set_layout
  dEQP-VK.api.null_handle.destroy_pipeline_layout
  dEQP-VK.api.null_handle.destroy_query_pool
