Ka-Cheong Poon 9484203d25 net/rds: Fix info leak in rds6_inc_info_copy() ...

[ Upstream commit 7d0a06586b ]

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: 3eb450367d ("rds: add type of service(tos) infrastructure")
Fixes: b7ff8b1036 ("rds: Extend RDS API for IPv6 support")
