IB: refcount race fixes Fix race condition during destruction calls to avoid possibility of accessing object after it has been freed. Instead of waking up a wait queue directly, which is susceptible to a race where the object is freed between the reference count going to 0 and the wake_up(), use a completion to wait in the function doing the freeing.
