* Fix a bug in mbedtls_asn1_store_named_data() where it would sometimes leave
an item in the output list in an inconsistent state with val.p == NULL but
val.len > 0. This impacts applications that call this function directly,
or indirectly via mbedtls_x509_string_to_names() or one of the
mbedtls_x509write_{crt,csr}_set_{subject,issuer}_name() functions. The
inconsistent state of the output could then cause a NULL dereference either
inside the same call to mbedtls_x509_string_to_names(), or in subsequent
users of the output structure, such as mbedtls_x509_write_names(). This
only affects applications that create (as opposed to consume) X.509
certificates, CSRs or CRLS, or that call mbedtls_asn1_store_named_data()
directly. Found by Linh Le and Ngan Nguyen from Calif.
