[PATCH] kernel/workqueue: Use __printf markup to silence compiler in function 'alloc_workqueue'

[Mathieu Malaterre]

Silence warnings (triggered at W=1) by adding relevant __printf attributes.

  kernel/workqueue.c:4249:2: warning: function 'alloc_workqueue' might be a 
candidate for 'gnu_printf' format attribute [-Wsuggest-attribute=format]
