[libvirt] [PATCH 1/2] Revert "network: Check for QOS before blindly using it"

[Erik Skultety]

This reverts commit f4db846c32c0a1e99a0f62b340273e48f8a98ed3.

This patch results in the following error when trying to start
essentially any VM with default network:

unsupported configuration: QOS must be defined for network 'default'

Coverity didn't see that the bandwidth == NULL it complained about in
virNetDevBandwidthPlug was already checked properly in
networkCheckBandwidth, thus causing networkPlugBandwidth to return 0
and finish before a call to virNetDevBandwidthPlug would have been even
made.
