Set subslots_per_pchan_vamos[GSM_PCHAN_OSMO_DYN] = 0
VAMOS secondary lchans are to be used specifically when the osmocom dyn TS is set to pchan_is=TCH_{F,H}. Setting secondary subslots for OSMO_DYN TS is not needed since it's only used to initialize the TS, and OSMO DYN already initializes 8 subslots (subslots_per_pchan[GSM_PCHAN_OSMO_DYN]=8). Otherwise, ts_setup_lchans() will try to initialize 8+2 lchans on the TS, which is more than needed and will access out of bounds in the array.
