panvk: Call vk_free on queue array instead of vk_object_free

Mary Guillemard requested to merge marysaka/mesa:panvk-fix-queue-double-free into main

What does this MR do and why?

panvk: Call vk_free on queue array instead of vk_object_free

This is allocated using vk_alloc and isn't a vk_object.
This fixes an invalid free that could manifest as a double free error.

Signed-off-by: Mary Guillemard <mary.guillemard@collabora.com>
Fixes: 5b0ff2643f2 ("panvk: Make the device creation/destruction per-arch")

Also changed queue array allocation to use vk_zalloc.
