numa_clear_kernel_node_hotplug() uses memblock_set_node() without checking for failures. memblock_set_node() is a complex function that might extend the memblock array - which extension might fail - so check for this possibility. It's not supposed to happen (because realistically if we have so little memory that this fails then we likely won't be able to boot anyway), but do the check nevertheless.
