mm/memblock: repeat setting reserved region nid if array is doubled
Commit 61167ad5fecd ("mm: pass nid to reserve_bootmem_region()") introduce
a way to set nid to all reserved region.
But there is a corner case it will leave some region with invalid nid.
When memblock_set_node() doubles the array of memblock.reserved, it may
lead to a new reserved region before current position. The new region
will be left with an invalid node id.
Repeat the process when detecting it.
Fixes: 61167ad5fecd ("mm: pass nid to reserve_bootmem_region()")
