openssl: don’t call CRYTPO_cleanup_all_ex_data
The OpenSSL function CRYTPO_cleanup_all_ex_data() cannot be called multiple times without crashing - and other libs might call it! We basically cannot call it without risking a crash. The function is a no-op since OpenSSL 1.1.0. Not calling this function only risks a small memory leak with OpenSSL < 1.1.0. Bug: https://curl.haxx.se/mail/lib-2016-09/0045.html Reported-by: Todd Short
