func (T) WipeMD 

func (t T) WipeMD() error

WipeMD executes the `wipe-md` drbd command.

Ignore the exit code `20`: 

Returned when the sub dev is not found.
No need to fail, as the sub dev is surely flagged for unprovision too,
which will wipe metadata.
This situation happens on unprovision on a stopped instance, when drbd
is stacked over another (stopped) disk resource.
