Remove duplicate cmd.Run()

There was a duplicate cmd.Run() that somehow went unnoticed. It was also
missing an error check, so it was in the code but had no ill effects.
In 86bfacd253 the error check was added.
This caused it to fail every time sure to the cmd already being ran.

Remove the duplicate cmd.Run() altogether.
