[Qemu-trivial] [PATCH 1/2] qcow2-snapshot: Change filter function to avoid NULL parameter when a snapshot will be created.

[Julio Faracco]

This is a trivial patch to change the filter 'find_snapshot_by_id_and_name'
to 'find_snapshot_by_id_or_name'. The field 'Name' is not required. So this
change avoid NULL parameters. And use the correct function to filter.
