Commit 08295b3b5bee ("Implement an algorithm choice for Wound-Wait
mutexes") introduced a reference in the documentation to a function
that was removed in an earlier commit.
It also forgot to remove a call to debug_mutex_add_waiter() which is now
unconditionally called by __mutex_add_waiter().
Fix those issues.
