[PATCH 5/9] media: rzg2l-cru: Move active_slot reset into rzg2l_cru_set_stream()

[Tommaso Merciai]

active_slot tracks the current DMA slot index and must always be reset
to zero before starting a new stream. Previously callers were responsible
for this reset before each rzg2l_cru_set_stream(cru, 1) invocation.

Move the reset inside rzg2l_cru_set_stream() so the invariant is
enforced in a single place and future callers cannot accidentally omit
it.
