mgr/dashboard: fix smart data error

the error in the log was this

```
"/usr/share/ceph/mgr/dashboard/services/ceph_service.py", line 253, in _get_smart_data_by_device
May 06 07:38:39 occldlr750-1.occl208.lab conmon[2142938]:     svc_type, svc_id = daemon.split('.')
May 06 07:38:39 occldlr750-1.occl208.lab conmon[2142938]: ValueError: too many values to unpack (expected 2)
```

on the cluster, the output of `ceph device ls-by-host` looks like this

```
ceph: root@occldlr750-1 /]# ceph device ls-by-host occldlr750-1.occl208.lab

```

the first device is mon and its name is mon.occldlr750-1.occl208.lab.

In our dashboard code, when fetching the smart data we have a line like
this

`svc_type, svc_id = daemon.split('.')`

so for the mon the output of `daemon.split('.') will be ['mon', 'occldlr750-1', 'occl208', 'lab']. The svc_id gets split into three because of the split. I am changing that and giving the criteria as splitting only on the first occurence of the dot and the considering everything that comes after the dot as the svc_id of the device.
