[Qemu-devel] [PATCH 3/4] qcow2: Drop debugging dump_refcounts()

[Eric Blake <eblake@redhat.com>]

It's been #if 0'd since its introduction in 2006, commit 585f8587.
We can revive dead code if we need it, but in the meantime, it has
bit-rotted (for example, not checking for failure in bdrv_getlength()).
