Check type of otherName value in PKINIT SAN code
In crypto_retrieve_X509_sans(), when we process a general name of type
AnotherName, check the ASN.1 type of the value before retrieving the
sequence or string pointer and length. Otherwise the function may
dereference a null or invalid pointer and crash. Discovered by
Alexandru-Ionut Jipa using Claude.
