memblock: Reimplement __memblock_remove() using memblock_isolate_range()
__memblock_remove()'s open coded region manipulation can be trivially
replaced with memblock_islate_range(). This increases code sharing
and eases improving region tracking.
This pulls memblock_isolate_range() out of HAVE_MEMBLOCK_NODE_MAP.
Make it use memblock_get_region_node() instead of assuming rgn->nid is
available.
-v2: Fixed build failure on !HAVE_MEMBLOCK_NODE_MAP caused by direct
rgn->nid access.
