drm/amdgpu/vm: Check PRT uAPI flag instead of PTE flag 



This fixes sparse mappings (aka. partially resident textures).

Check the correct flags.
Since a recent refactor, the code works with uAPI flags (for
mapping buffer objects), and not PTE (page table entry) flags.

Fixes: 6716a823 ("drm/amdgpu: rework how PTE flags are generated v3")
