workqueue: Annotate alloc_workqueue_va() with __printf(1, 0) 



alloc_workqueue_va() forwards its va_list to __alloc_workqueue() which
ultimately feeds vsnprintf(). __alloc_workqueue() already carries
__printf(1, 0); the new wrapper needs the same annotation so format
string checking propagates through the forwarding.

Fixes: 0de4cb47 ("workqueue: fix devm_alloc_workqueue() va_list misuse")
