[PATCH v3 2/7] media: qcom: iris: fix state-change debug log printing stale value

[Vishnu Reddy]

From: Dikshita Agarwal <dikshita.agarwal@xxxxxxxxxxxxxxxx>

The state‑change debug log in iris_inst_change_state() always prints the
same value for the old and new state, rendering it useless for
debugging. This happens because the state is updated before the log is
emitted.

Log the transition before updating the state so the previous value is
preserved, consistent with the existing sub‑state handling.
