A CodeChecker report from Clang's CTU analysis indicated that we were assigning uninitialized values in crypto_create_ctx_template() when we call it from zio_crypt_key_init(). This occurs because the ->cm_param and ->cm_param_len fields are uninitialized. Thankfully, the uninitialized values are only used in the skein via KCF_PROV_CREATE_CTX_TEMPLATE() -> skein_create_ctx_template() -> skein_mac_ctx_build() -> skein_get_digest_bitlen(), but that should not be called from here. We fix this to avoid a possible trap should this code change in the future. The FreeBSD version of zio_crypt_key_init() is unaffected.
