venus: Use vk_object_id as blob_id for guest_vram device memory alloc

blob_id == 0 does not refer to an existing VkDeviceMemory and implies
a shmem allocation. So for guest_vram device memory allocations, 0 is
not a valid blob id and must be greater than 0.

Therefore, set vk_object_id as blob_id for guest_vram device memory
allocations. Considering that vk_object_id made from valid pointer, it
will be always greater than 0.
