As of the previous commit, when a zero-length (string) parameter is present in the parameters passed to a provider for a given operation, we will produce an object corresponding to that zero-length parameter, indicating to the underlying cryptographic operation that the parameter was passed. However, rsa_cms_decrypt() was relying on the previous behavior, and unconditionally tried to call EVP_PKEY_CTX_set0_rsa_oaep_label() even when the implicit default label was used (and thus the relevant local variable was still NULL). In the new setup that distinguishes present-but-empty and absent more clearly, it is an error to attempt to set a NULL parameter, even if it is zero-length. Exercise more caution when setting parameters, and do not call EVP_PKEY_CTX_set0_rsa_oaep_label() when there is not actually a label provided.
