virDevMapperGetTargetsImpl: Be tolerant to kernels without DM support

https://bugzilla.redhat.com/show_bug.cgi?id=1591732

If kernel is compiled without CONFIG_BLK_DEV_DM enabled, there is
no /dev/mapper/control device and since dm_task_create() actually
does some ioctl() over it creating a task may fail.
To cope with this handle ENOENT and ENODEV gracefully.
