[libvirt] [PATCH 2/2] virNetDevBandwidthUnplug: Don't leak @cmd

[Michal Privoznik]

When removing a TAP device, the associated bandwidth settings are
removed. Currently, the /sbin/tc is used for that. It is spawned
several times. Moreover, we use the same @cmd variable to
construct the command and its arguments. That means we need to
virCommandFree(cmd); prior to each virCommandNew(TC); which
wasn't done.
