osmo-bts-trx: fix hopping pointer bug in trx_sched_fn()

In change [1] together with the actual implementation I introduced
a serious bug to trx_sched_fn(): if a timeslot is configured to use
frequency hopping, both 'pinst' and 'l1h' pointers are *overwriten*
in the inner loop, so the Downlink burst is re-directed to the
approproate PHY instance.  However, if a subsequent timeslot is not
hopping, the Downlink burst would be re-directed to the wrong PHY
instance because both pointers were overwriten during a previous
iteration.

Let's add another 'struct phy_instance' pointer to the inner loop,
so it's properly re-initialized for each timeslot iteration.
