osmo-bts-trx/scheduler: refactor dummy burst scheduling
This change facilitates the upcoming freq. hopping implementation,
in particular scheduling of dummy bursts on C0 with hopping time-
slots. One problem is that we cannot know in advance, whether to
send a dummy burst on a given timeslot unless all transceivers are
processed. For example, trx#3 may want to send a normal burst on
ARFCN of trx#0 (C0), while we have already sent a dummy burst...
Another important aspect is that we shall not be sending dummy
bursts on transceivers other than C0. Scheduling dummy bursts
from _sched_dl_burst() in the context of a single hopping timeslot
of a single transceiver leaves trx_sched_fn() no way to know
whether it's a dummy burst or something else.
Let's solve both problems by moving dummy burst scheduling logic
from _sched_dl_burst() to trx_sched_fn(). Maintain C0 slot-mask
in the inner (per-trx) loop, so that we can fill missing bursts
with dummy bursts afterwards.
