Suppress errors about undocumented asn1_d2i_read_bio
Suppress errors about undocumented asn1_d2i_read_bio

asn1_d2i_read_bio is exported by libcrypto but is only intended
for internal usage, and does not exist in our public headers.
Therefore we suppress errors about it being a newly added
undocumented symbol.
