locking/mutex, sched/wait: Fix the mutex_lock_io_nested() define 

Mike noticed this bogosity:

 > > +# define mutex_lock_nest_io(lock, nest_lock) mutex_io(lock)
 >                                                 ^^^^^^^^^^^^^^ typo

This new locking API is not used yet, so this didn't trigger in testing.

Fix it.
