We can make qcowXGetBackingStore() return the enum type instead of plain
int. But that can be done in a follow up (trivial) patch. When doing
that, both qcow1GetBackingStore() and qcow2GetBackingStore() and also
getBackingStore() callback can use the same tretement then.

Ah, you're removing some functions, but you get the idea.
