[PATCH v3 0/2] drm/xe: Consolidate VM initialization logic

[Piórkowski, Piotr]

From: Piotr Piórkowski <piotr.piorkowski at intel.com>

This series refactors VM creation to consolidate initialization logic
into xe_vm_create, ensuring consistency across all VM creation paths.

This also fixes a bug introduced in
"drm/xe: add XE_BO_FLAG_PINNED_LATE_RESTORE"
which incorrectly assumed that vm->xef is initialized before PTs are
created.

v1 -> v2:
 - take reference to the xe file object only when xef is not NULL
 - release the reference to the xe file object on the error path (Matthew)
 - move usm.asid and the pt tracking to xe_create_vm - new patch (Matthew)
 - add this cover letter
v2 -> v3:
 - removed unnecessary duplicate BO tracking code (it is alredy done in xe_pt_create)
 - using the local variable xef to verify whether the VM is being created
   by userspace
