ASoC: msm: qdsp6v2: Fix crash during WFD playback and SSR

Browse source 
Device crash is observed for consecutive SSR's triggered during WFD
playback. This is due to callback functions registered by afe client
aren't reset during the first SSR and the same callback functions are
being used for the next SSR event, resulting access in freed data.
Fix this issue by resetting the callback functions during SSR.
