[igt-dev] [PATCH v3 38/57] xe: Do not stash vram_size

[Francois Dugast]

From: Rodrigo Vivi <rodrigo.vivi at intel.com>

Do not stash extra information. The queries are already stashed,
we just need to navigate the structs.

This is a preparation patch to move the memory masks from GT
to Engine. So, let's avoid having extra stashed arrays.
