net: rds: use memset to optimize the recv
The function rds_inc_init is in recv process. To use memset can optimize the function rds_inc_init. The test result: Before: 1) + 24.950 us | rds_inc_init [rds](); After: 1) + 10.990 us | rds_inc_init [rds](); Acked-by: Santosh Shilimkar <santosh.shilimkar@oracle.com> Signed-off-by: Zhu Yanjun <yanjun.zhu@oracle.com> Signed-off-by: David S. Miller <davem@davemloft.net>
