👑 DESCRIPTION 👑

Release the global PASID xarray lock and restore the previous interrupt state 💖

fr fr, that's the whole job: drop the lock, put the interrupt state back exactly how it was before. lock it, unlock it, restore the state — the sacred cycle 🙈✨

lowkey be a good citizen about this one — flags is literally the interrupt state from amdgpu_pasid_lock, and this function is what restores it. don't be out here making up your own value 🫶
