rtmutex: Fix comment about why new_owner can be NULL in wake_futex_pi()
The comment about why rt_mutex_next_owner() can return NULL in wake_futex_pi() is not the normal case. Tracing the cause of why this occurs is more likely that waiter simply timedout. But because it originally caused contention with the futex, the owner will go into the kernel when it unlocks the lock. Then it will hit this code path and rt_mutex_next_owner() will return NULL.
