vty: remove groundless statement about filler type 'dummy' 

Dummy bursts have nothing to do with A5/x encryption, and I see
no reason why (and how?!?) would using that filler type break
encryption in osmo-bts-trx.  I asked the author of this code
back in August 2020 [1], and so far didn't get any response.
