kho: initialize preserved memory map radix tree earlier

Browse source

Currently the preserved memory radix tree is initialized from
kho_memory_init(), which happens relatively late in MM init. In a coming
patch, the tree will be used from kho_memory_init_early(). Move the tree
initialization there.

Simplify some of the code in kho_mem_retrieve() by getting rid of the
err variable and jumping to err directly.
