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.
Fixes: 647810ec2476 ("drm/panthor: Add the MMU/VM logical block")
