mgcp_vty: fix endpoint number configuration
At the moment the number of possible E1 endpoints (depends on the number
of E1 timeslots that should be used) is hardcoded and the configuration
of the number of virtual endpoints has an off-by-one problem.
For the E1 timeslots one might choose not to occupy all E1 timeslots of
once. A one TRX E1 BTS usually requires 3 E1 timeslots. One as D-Channel
timeslot and two to cover the voice channels. The voice channels
timeslots need to be set up in osmo-mgw, while the D-Channel timeslot
must not be touched. The VTY config needs to be able to reflect that.
