scheduler_trx: Fix erroneous multiply-by-four

Commit acefd0586e5d463b2e7a6a039131994bc12573fc introduced the "toa256"
resolution change.

Before the change, _sched_compose_ph_data_ind() used quarter-bits as
units, so multiplying the old "toa" value by four made sense.

However, after said change, the value is in 1/256th of bits, and hence
we need to report the toa256 value without any multiply-by-four.
