    Fix for re-sync logic in reading packet from backend.
    
    read_kind_from_backend(), which reads message kind from backend,
    re-syncs backend nodes when a ready for query message is
    received. Unfortunately it forgot to call
    pool_pending_message_pull_out() to delete sync pending message. This
    leads to random stuck while reading packets from backend. Fix this to
    call pool_pending_message_pull_out().
