performance/write-behind: remove redundant traversal of write-requests in the wind list in wb_ sync.
- no need of getting the total_count of number of requests in the list.
Even if there is a single request, we need to sync it.
Signed-off-by: Anand V. Avati <avati@dev.gluster.com>
BUG: 276 (write behind needs to be optimized.)
