Fix ex_data locks issue Travis identified a problem with freeing the ex_data locks which wasn't quite right in ff2344052. Trying to fix it identified a further problem: the ex_data locks are cleaned up by OPENSSL_cleanup(), which is called explicitly by CRYPTO_mem_leaks(), but then later the BIO passed to CRYPTO_mem_leaks() is freed. An attempt is then made to use the ex_data lock already freed. Reviewed-by: Tim Hudson <tjh@openssl.org>
