[PATCH 1/3] qemuSnapshotForEachQcow2: Don't initialize 'nrollback'
The variable holds the amount of disks to roll back the snapshot for.
The value must be set before the code jumps to the 'rollback:' label so
the best situation is to not initialize it and let the compiler catch
errors rather than initialize the unsigned variable to -1 and let it
crash.
