genirq/affinity: Remove const qualifier from node_to_cpumask argument

When CONFIG_CPUMASK_OFFSTACK isn't enabled, 'cpumask_var_t' is as

'typedef struct cpumask cpumask_var_t[1]',

so the argument 'node_to_cpumask' alloc_nodes_vectors() can't be declared
as 'const cpumask_var_t *'

Fixes the following warning:

   kernel/irq/affinity.c: In function '__irq_build_affinity_masks':
     alloc_nodes_vectors(numvecs, node_to_cpumask, cpu_mask,
                                  ^
   kernel/irq/affinity.c:128:13: note: expected 'const struct cpumask (*)[1]' but argument is of type 'struct cpumask (*)[1]'
    static void alloc_nodes_vectors(unsigned int numvecs,
                ^
