[ruby/openssl] ossl.c: avoid using sk_*() functions with NULL
Always use explicit NULL checks before interacting with STACK_OF().
Even though most OpenSSL functions named sk_() do not crash if we pass
NULL as the receiver object, depending on this behavior would be a bad
idea.
Checks for a negative number return from sk_*_num() are removed. This
can only happen when the stack is NULL.
ossl_*_sk2ary() must no longer be called with NULL.
