+    qemu: Fix logic bug in inactive snapshot deletion
+    
+    Commit 926563dc3a6 which refactored the function call deleting the
+    snapshot's on disk state introduced a logic bug, which skips over the
+    deletion of libvirt metadata after the disk state deletion is done.
+    
+    To fix it we must not return early.
