x86/mm: Fix cpumask_of_node() error condition
When CONFIG_DEBUG_PER_CPU_MAPS=y we validate that the @node argument of
cpumask_of_node() is a valid node_id. It however forgets to check for
negative numbers. Fix this by explicitly casting to unsigned int.
(unsigned)node >= nr_node_ids
verifies: 0 <= node < nr_node_ids
Also ammend the error message to match the condition.
