Alberto Garcia 9b765486b7 qcow2: Read refcount before L2 table in expand_zero_clusters_in_l1() 
At the moment it doesn't really make a difference whether we call
qcow2_get_refcount() before of after reading the L2 table, but if we
want to support L2 slices we'll need to read the refcount first.

This patch simply changes the order of those two operations to prepare
for that. The patch with the actual semantic changes will be easier to
read because of this.
