Don't read it->funcs without checking it->itype.

it->funcs is only an ASN1_AUX for ASN1_ITYPE_SEQUENCE and
ASN1_ITYPE_CHOICE. Fortunately, the other possible types for it->funcs
are larger than ASN1_AUX and we don't touch the result when we
shouldn't, so this is merely a strict aliasing violation.
