mm: numa_clear_kernel_node_hotplug: Add NUMA_NO_NODE check for node id
The acquired memory blocks for reserved may include blocks outside of
memory management. In this case, the nid variable is set to NUMA_NO_NODE
(-1), so an error occurs in node_set(). This adds a check using
numa_valid_node() to numa_clear_kernel_node_hotplug() that skips
node_set() when nid is set to NUMA_NO_NODE.
