block/qcow2: Make get_refcount() global

Reading the refcount of a cluster is an operation which can be useful in
all of the qcow2 code, so make that function globally available.

While touching this function, amend the comment describing the "addend"
parameter: It is (no longer, if it ever was) necessary to have it set to
-1 or 1; any value is fine.
