osmo-bts-trx: remove an 'else' branch in _sched_dl_burst() 

When I introduced this branch in change [1], I was under assumption
that PDCHs never have an associated 'struct gsm_lchan'.  This is
incorrect: the association actually happens during PDCH activation,
i.e. when osmo-pcu establishes connection over the PCUIF.

Enforcing attenuation of 0 dB for other channel types makes no sense.
