Ensure name not null in EVP_get_cipherbyname

This adds a check to EVP_get_cipherbyname which ensures that name
is not null when passed to OPENSSL_strcasecmp, which cannot handle
null values.

OpenSSL already ensures this in their implementation of
EVP_get_cipherbyname by using OBJ_NAME_get, so this improves parity.
