[PATCH 1/3] ipvs: fix timer in get_curr_sync_buff

[Simon Horman <horms@xxxxxxxxxxxx>]

From: Tinggong Wang <wangtinggong@xxxxxxxxx>

        Fix get_curr_sync_buff to keep buffer for 2 seconds
as intended, not just for the current jiffie. By this way
we will sync more connection structures with single packet.
