H A Dvfio_ccw_cp.cdiff 6246590230e9c1225d2ce8d0160376b4d5511281 Tue Jun 18 15:23:49 CDT 2019 Eric Farman <farman@linux.ibm.com> vfio-ccw: Skip second copy of guest cp to host

We already pinned/copied/unpinned 2K (256 CCWs) of guest memory
to the host space anchored off vfio_ccw_private. There's no need
to do that again once we have the length calculated, when we could
just copy the section we need to the "permanent" space for the I/O.
