Kernel: Take the RegionTree spinlock when inspecting tree from outside

Browse source 
This patch adds RegionTree::get_lock() which exposes the internal lock
inside RegionTree. We can then lock it from the outside when doing
lookups or traversal.

This solution is not very beautiful, we should find a way to protect
this data with SpinlockProtected or something similar. This is a stopgap
patch to try and fix the currently flaky CI.
