Yeah, it is but the original version is used on several places in node_device
so guess it's better to be consistent with the rest of the code. And although
it's slightly more efficient, I don't think it's a good idea to rewrite
existing code since it could lead into some ugly long lines, such as

    LINUX_SYSFS_FC_HOST_PREFIX "host%d" LINUX_SYSFS_VPORT_CREATE_POSTFIX
