crypto_acipher_sm2_dsa_sign() and crypto_acipher_sm2_dsa_verify() leak
some bignum memory due to missing calls to ecc_free().
This is all the more problematic that bignum allocations use a special
memory pool [1] that can easily cause deadlocks when misused.
This commit adds the missing calls.
[1] Commit a2eb5b55d169 ("libutils: add mempool API")
Fixes: 76c7ba4b9ff7 ("core: ltc: add support for SM2 DSA")
