powerpc: Fix write-after-destroy in lock elision [BZ #20822]
The update of *adapt_count after the release of the lock causes a race
condition when thread A unlocks, thread B continues and destroys the
mutex, and thread A writes to *adapt_count.
(cherry picked from commit e9a96ea1aca4ebaa7c86e8b83b766f118d689d0f)
(with changes from commit eb1321f291515dae75c83a40c39e775fdd38e97a)
