With commit 0c24e061196c ("mm: kmemleak: add rbtree and store physical
address for objects allocated with PA"), kmemleak started to put the
objects allocated with physical address onto object_phys_tree_root tree.
The kmemleak_free_part() therefore no longer worked as expected on
physically allocated objects (hyp_mem_base in this case) as it attempted to
search and remove things in object_tree_root tree.
Fix it by using kmemleak_free_part_phys() to unregister hyp_mem_base. This
fixes an immediate crash when booting a KVM host in protected mode with
kmemleak enabled.
