RDMA/usnic: Suppress a compiler warning
This patch avoids that the following compiler warning is reported when
building with gcc 8 and W=1:
drivers/infiniband/hw/usnic/usnic_fwd.c:95:2: warning: 'strncpy' output may be truncated copying 16 bytes from a string of length 20 [-Wstringop-truncation]
strncpy(ufdev->name, netdev_name(ufdev->netdev),
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
sizeof(ufdev->name) - 1);
~~~~~~~~~~~~~~~~~~~~~~~~
