dbus-sdr: Remove excessive `Failed to GetAll` error message
The `Failed to GetAll` message will happen if any of the sensor doesn't
have `Inventory.Decorator.Ipmi` dbus interface. Instead of making a
`GetAll` call to all sensors, we will check if the sensor have the
interface first before requesting it. This will remove the need to
attempt sigificantly amount of unnecessary dbus calls.
Tested:
ipmitool sdr return the same sensor as before, but with no excessive
error message.
There is also some performance gain after removing the extra dbus calls.
Before,
```
$ time ipmitool sdr | wc -l
346
real 0m13.786s
user 0m0.315s
sys 0m0.115s
$ time ipmitool sdr | wc -l
346
real 0m14.692s
user 0m0.274s
sys 0m0.196s
```
After,
```
$ time ipmitool sdr | wc -l
346
real 0m11.765s
user 0m0.205s
sys 0m0.155s
$ time ipmitool sdr | wc -l
346
real 0m11.403s
user 0m0.269s
sys 0m0.141s
```
