sh: fix memory corruption of unflattened device tree
unflatten_device_tree() makes use of memblock allocation, and therefore must be called before paging_init() migrates the memblock allocation data to the bootmem framework. Otherwise the record of the allocation for the expanded device tree will be lost, and will eventually be clobbered when allocated for another use. Signed-off-by: Rich Felker <dalias@libc.org>
