Fix ASN1_TYPE memory leak in asn1_multi()
In asn1_gen.c `asn1_multi()` function variable allocated as
`ASN1_TYPE *typ = generate_v3()` is not freed if
`if (!sk_ASN1_TYPE_push(sk, typ))` branch fails.
Bug found by x509v3 fuzzer MFAIL test.
Example input:
```
[default]
1.2.3.4 = ASN1:SEQUENCE:items
[items]
value = INTEGER:1
```
