    event/epoll: Add back socket for polling of events immediately after
                 reading the entire rpc message from the wire

    Currently socket is added back for future events after higher layers
    (rpc, xlators etc) have processed the message. If message processing
    involves signficant delay (as in writev replies processed by Erasure
    Coding), performance takes hit. Hence this patch modifies
    transport/socket to add back the socket for polling of events
    immediately after reading the entire rpc message, but before
    notification to higher layers.
