[ltt-dev] [PATCH v2] Remove ltt-armall/disarmall's unwanted errormessages

Actually, I considered about return value, but if other kind of error
happened, I think it is better to show errormsg to user.
If we judge on return value, user will see "Already connect" if other
 error happened.

Judge on "write error: File exists" maybe little iffy, but on worst case,
it will show whole errormessage to user(maybe the best choose).

Thanks!
