drm/xe/pf: Update the LMTT when freeing VF GT config

mwajdecz · Thomas Hellström · commit 0698ff57bf32 · 2024-06-04T16:31:24.000+02:00
The LMTT must be updated whenever we change the VF LMEM configuration. We missed that step when freeing the whole VF GT config, which could result in stale PTE in LMTT or LMTT PT object leaks. Fix that.
