    Bug-fix: correct SHM memory size in Nemesis Win_gather_info().
    
    In the Nemesis implementation of Win_gather_info(), we allocate
    a memory region on SHM to store window information for other
    processes, so that all processes on the same node can share
    those information. However, previously the memory size was
    incorrectly set as O(node_comm_size), which should be O(comm_size).
    This patch fixed this bug.

    Bug-fix: correct local/remote completion in Win_flush_local.
    
    The original implementation in Win_flush_local counts number
    of total local completion and remote completion needed to
    wait, and then waiting for current local/remote completion
    count to reach those values. There is a bug that we should
    initialize the current count to zero in each while loop,
    otherwise the targets that are already completed will be
    count again and we failed to wait for some targets to be
    completed. This patch fixes this issue.
