Revert "qemu: Don't repeat virDomainObjEndAPI in qemuDomainBlockPull"

Browse Source 
This reverts commit 421c9550f5

qemuDomainBlockPullCommon calls virDomainObjEndAPI internally so the
original commit made us shed two references of @vm instead of one
getting us into a premature free of @vm.

This is not a straight revert as qemuDomainBlockPull was modified
meanwhile. I've also added a warning comment that @vm is consumed.
