iw_cxgb4: initialize ibdev.iwcm->ifname for port mapping
The IWCM uses ibdev.iwcm->ifname for registration with the iwarp port map daemon. But iw_cxgb4 did not initialize this field which causes intermittent registration failures based on the contents of the uninitialized memory. Fixes: 170003c894d9 ("iw_cxgb4: remove port mapper related code") Signed-off-by: Steve Wise <swise@opengridcomputing.com> Signed-off-by: Doug Ledford <dledford@redhat.com>
