The ttm_bo_init_reserved() functions returns -ENOSPC if the size is too big
to add vma. The direct function that returns -ENOSPC is
drm_mm_insert_node_in_range().
To handle the same error as other code returning -E2BIG when the size is
too large, it converts return value to -E2BIG.

There's a complete rewrite of the core context handling in
v6.2-rc1. find_pmu_context function used in this commit doesn't
exist anymore. Also, let's first trust the upstream component,
then work with them to get the issue solved if still present,
