drm/panthor: Unlock the locked region before disabling an AS
An AS can be disabled in the middle of a VM operation (VM being
evicted from an AS slot, for instance). In that case, we need the
locked section to be unlocked before releasing the slot.
v2:
- Add an lockdep_assert_held() in panthor_mmu_as_disable()
- Collect R-bs
v3:
- Don't reset the locked_region range in the as_disable() path
Fixes: 6e2d3b3e8589 ("drm/panthor: Add support for atomic page table updates")
