mm/nobootmem: free_all_bootmem again
get_allocated_memblock_reserved_regions_info() should work if it is
compiled in. Extended the ifdef around
get_allocated_memblock_memory_regions_info() to include
get_allocated_memblock_reserved_regions_info() as well. Similar changes
in nobootmem.c/free_low_memory_core_early() where the two functions are
called.
