[pnfs] [PATCH 6/8] Changed xs_tcp_data_recv() to call xs_tcp_read_calldir()

[iyer at netapp.com]

From: Rahul Iyer <iyer at netapp.com>

Modified the state machine in xs_tcp_read_calldir() to call
xs_tcp_read_calldir() when the XPRT_COPY_CALLDIR is set. This enables the
call/reply flag to be read in as a separate entity and not as a part of the
"data"
