EVP_CipherInit_ex(): normalize EVP_CIPHER_CTX_ctrl() error check

While EVP_CIPHER_CTX_ctrl() can return a negative value this can't
actually happen currently as all ciphers with EVP_CIPH_CTRL_INIT set
normalize the EVP_CTRL_INIT return value to boolean in their ctrl()
methods. Still, this check looks weird in grep, so align it.
