On dual-stack secondary VNICs, the IPv6 address was incorrectly configured with the IPv4 subnet prefix length (e.g. /24 instead of /64). This happened because `network` was computed from `subnetCidrBlock` (IPv4) and reused for both address families.

On OCI instances with IPv6 enabled on a secondary VNIC,
_add_network_config_from_opc_imdsused a singlenetworkvariable (derived from the IPv4subnetCidrBlock) for both IPv4 and IPv6 prefix lengths. This caused the IPv6 address to be configured with the IPv4 prefix length.OCI's IMDS provides
ipv6SubnetCidrBlockwith the correct IPv6 prefix, but it was never read.The fix moves the
networkassignment inline to each address block, so IPv4 usessubnetCidrBlockand IPv6 usesipv6SubnetCidrBlock.
