qcow2: Make qcow2_free_any_clusters() free only one cluster
This function takes an L2 entry and a number of clusters to free.
Although in principle it can free any type of cluster (using the L2
entry to determine its type) in practice the API is broken because
compressed clusters have a variable size and there is no way to free
more than one without having the L2 entry of each one of them.
The good news all callers are passing nb_clusters=1 so we can simply
get rid of that parameter.
