[libvirt] [PATCH 1/8] Remove superfluous usage of virDomainDeviceInfoNeedsFormat

[Ján Tomko]

This function returns false if virDomainDeviceInfoFormat
would not format anything.

Using it as the sole condition to decide whether to call
virDomainDeviceInfoFormat or not is pointless, since
the conditions are repeated in virDomainDeviceInfoFormat.
