    [CELEBORN-1818] Fix incorrect timeout exception when waiting on no pending 
writes
    
    ### What changes were proposed in this pull request?
    Do not throw "Wait pending actions timeout" exception when waiting pending 
writes times out.
    
    ### Why are the changes needed?
    When pendingWrites is reduced to zero, the method waitOnNoPending will jump 
out of the while loop. Meanwhile, if new PushData/PushMergedData request comes, 
pendingWrites will increment and be larger then zero. As a result, "wait 
pending actions timeout" exception will be thrown in waitOnNoPending.
    
    ### Does this PR introduce _any_ user-facing change?
    No
    
    ### How was this patch tested?
    manual test
    
    Closes #3049 from littlexyw/fix_wait_pending_writes_timeout.
