CVE-2024-53080: drm/panthor: Lock XArray when getting entries for the VM
In the Linux kernel, the following vulnerability has been resolved:
drm/panthor: Lock XArray when getting entries for the VM
Similar to commit cac075706f29 ("drm/panthor: Fix race when converting group handle to group object") we need to use the XArray's internal locking when retrieving a vm pointer from there.
v2: Removed part of the patch that was trying to protect fetching the heap pointer from XArray, as that operation is protected by the @pool->lock.
