qemu-iotests: ignore leaks on failure paths in 026

Browse source 
Upcoming asynchronous handling of sub-parts of qcow2 requests will
change number of leaked clusters and even make it racy. As a
preparation, ignore leaks on failure parts in 026.

It's not trivial to just grep or substitute qemu-img output for such
thing. Instead do better: 3 is a error code of qemu-img check, if only
leaks are found. Catch this case and print success output.
