rds: fix an infoleak in rds_inc_info_copy
The last field "flags" of object "minfo" is not initialized. Copying this object out may leak kernel stack data. Assign 0 to it to avoid leak. Signed-off-by: Kangjie Lu <kjlu@gatech.edu> Acked-by: Santosh Shilimkar <santosh.shilimkar@oracle.com> Signed-off-by: David S. Miller <davem@davemloft.net>
