futex: Fix WARN_ON() test for UP
An update of the futex code had a WARN_ON(!spin_is_locked(q->lock_ptr)) But on UP, spin_is_locked() is always false, and will trigger this warning, and even worse, it will exit the function without doing the necessary work. Converting this to a WARN_ON_SMP() fixes the problem.
