TEST-64-UDEV-STORAGE: several fixlets for check_device_units()

Browse Source 
To suppress the following warnings in case check_device_unit() failed e.g.
when the device is already removed:
```
sed: couldn't write 130 items to stdout: Broken pipe
awk: write failure (Broken pipe)
awk: close failed on file "/dev/stdout" (Broken pipe)
```
