strncpy(3) does not NUL-terminate the destination if the source is of
the same length or longer then the specified size.
The source of these copies are retrieved from
sepol_ibendport_alloc_ibdev_name(), which allocates a fixed amount of
IB_DEVICE_NAME_MAX bytes.
Reduce the size to copy by 1 of all memory regions allocated by
sepol_ibendport_alloc_ibdev_name().
