remoteproc: qcom: q6v5: Update running state before requesting stop
commit 5b7be880074c73540948f8fc597e0407b98fabfa upstream.
Sometimes the stop triggers a watchdog rather than a stop-ack. Update
the running state to false on requesting stop to skip the watchdog
instead.
Error Logs:
$ echo stop > /sys/class/remoteproc/remoteproc0/state
ipa 1e40000.ipa: received modem stopping event
remoteproc-modem: watchdog received: sys_m_smsm_mpss.c:291:APPS force stop
