use-after-free on failing RSA_generate_key_ex()

Reported by Yuan Kang.

When we generate a key, if openssl fails to generate an RSA key, we currently retain a dangling pointer to the previous (uninitialized) key value. The impact here should be limited to a difficult-to-trigger crash, if OpenSSL is running an engine that makes key generation failures possible, or if OpenSSL runs out of memory.

To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
