The rds6_inc_info_copy() function has a couple struct members which
are leaking stack information. The ->tos field should hold actual
information and the ->flags field needs to be zeroed out.
Fixes:
3eb450367d08 ("rds: add type of service(tos) infrastructure")
Fixes:
b7ff8b1036f0 ("rds: Extend RDS API for IPv6 support")
