[PATCH 2/6] qemuSnapshotCreateActiveInternal: Fix error logic

[Peter Krempa via Devel]

From: Peter Krempa <pkre...@redhat.com>

The 'ret' variable is set to 0 before a call which can theoretically
fail. Not in practice really as the failure scenarion includes only
object initialization.

Since the code already has another variable for checking monitor returns
use that one properly so that the code makes sense.
