CONSULT_MEM_ADVISE_PREF_LOC\n\nWhen prefetch region is DRM_XE_CONSULT_MEM_ADVISE_PREF_LOC for a BO VMA,\nthe code used it as an index into region_to_mem_type[], causing an\nout-of-bounds access since the value is -1.\n\nResolve the preferred location for BO VMAs directly: local VRAM on dGFX\n(using the BO's tile placement) or system memory on iGPU.\n\nDiscovered using AI-assisted static analysis confirmed by Intel Product\nSecurity.\n\nv2:\n-Fix null dereference\n\n(cherry picked from commit
