[libvirt] [PATCH] qemu: Use iohelper during restore
Commit afe6e58 & c4caab53 made necessary changes to use io-helpers
during save and restore. The commit c4caab53 missed to remove the
redundant check in qemuDomainSaveImageOpen() because of which
virFileWrapperFdNew() is not called if bypass_cache is false.
