block: use the standard 'ret' instead of 'result'
Most QEMU code uses 'ret' for function return values. The VDI driver uses a mix of 'result' and 'ret'. This cleans that up, switching over to the standard 'ret' usage. Reviewed-by: Max Reitz <mreitz@redhat.com> Signed-off-by: Jeff Cody <jcody@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
