fix data race choosing next key slot in pthread_key_create
commit 84d061d5a31c9c773e29e1e2b1ffe8cb9557bc58 wrongly moved the
access to the global next_key outside of the scope of the lock. the
error manifested as spurious failure to find an available key slot
under concurrent calls to pthread_key_create, since the stopping
condition could be met after only a small number of slots were
examined.
