drm/xe: Standardize pat_index to u16 type

Browse Source 
Ensure all pat_index definitions consistently use u16 type across
the XE driver. This addresses two remaining instances where pat_index
was incorrectly typed:

- xe_vm_snapshot structure used int for pat_index field
- xe_device pat.idx array used u32 instead of u16

This cleanup improves type consistency and ensures proper alignment
with the PAT subsystem design.
