[pnfs] [PATCH 1/8] Added XPRT_COPY_CALLDIR flag

[iyer at netapp.com]

From: Rahul Iyer <iyer at netapp.com>

This flag is used in the state machine implementation in xs_tcp_data_recv() to
read in the call/reply flag. This flag will be used to recognize whether the
rpc packet received is a reply to a call the client made or a callback from the
server received on the backchannel.
