drm/xe: reference VM from PT BOs

Browse source

PT BOs share the VM's dma-resv and therefore must keep the VM alive
until all PT BOs are destroyed.
 
Take a VM reference from PT BOs to ensure the shared dma-resv remains
valid for the lifetime of the BOs. Scope the change to PT BOs rather
than all kernel BOs to minimize risk and avoid extending VM lifetimes
unnecessarily.
