    [TC-136] Fixes a logic bug that prevented the easy case for finding bond speed, and handle the case where the CentOS 7.3 3.10.0-514 kernel uses lower_X as a pointer to enslaved interfaces, while retaining the slave_X case from earlier kernels.

> CentOS 7.2 ships with kernel 3.10.0-327, while 7.3 has 3.10.0-514. The former provides one way to find slave interfaces via sysfs:
> {code}/sys/class/net/<bond>/slave_<enslaved_interface>{code}
> ...while the latter provides another:
> {code}/sys/class/net/<bond>/lower_<enslaved_interface>{code}
> A bug in astats is causing us to skip the easiest means of obtaining the speed, falling through to one that is known to work only with 3.10.0-327 and prior kernels.
