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.
