x86/mm/numa: Check for failures in numa_clear_kernel_node_hotplug()

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.
