anv/xe: Consider pat_index while unbinding the bo

Browse source 
Xe KMD also checks if cpu_caching caching set during bo creationg
matches with caching of the PAT index set in the VM unbind.

This was being unnoticed until now by luck and lack of testing in MTL.

So here always setting PAT index for all VM operations that has a bo
associated.

v2: (Jose)
- Move pat_index little bit up
- Copy commit message from iris patch

Fixes: 19439624d9 ("anv: Use DRM_XE_VM_BIND_OP_UNMAP_ALL to unbind whole bos")
