Subject: [PATCH] virNetDevBandwidthEqual: Make it more robust
So far the virNetDevBandwidthEqual() expected both ->in and ->out items
to be allocated for both @a and @b compared. This is not necessary true
for all our code. For instance, running 'update-device' twice over a NIC
with the very same XML results in SIGSEGV-ing in this function.
