osmo-bts-trx/scheduler: get rid of _sched_fcch_burst
According to 3GPP 45.002, section 5.2.4, a frequency correction
burst is basically a sequence of zeros. Since br->burst is already
zero-initialized, there is no need to maintain and memcpy() another
sequence of zeros into it. Just set the length.
