[PATCH 3/3] ipvs: fix get_curr_sync_buff

use time_after get the current buffer created more than the specified time.

time_before in get_curr_sync_buff(2 * HZ) will get the buffer created newly.
if curr_sb has been created more than 2*HZ then it will still sit in master.
so use time_after instead.
