ASoC: wcd_cpe_services: Fix the state propogation for OFFLINE state

Under normal operation, the cpe services state never goes to OFFLINE,
but during SSR handling, the state transitions to OFFLINE. Fix the
propogation of OFFLINE state transition to avoid erroneous CPE state
which can lead to unexpected issues.
