asoc: wcd-dsp-mgr: reinit ssr ready flag for adsp/wdsp ssr
When adsp/wdsp SSR happens, WDSP_SSR_TYPE_WDSP_DOWN/WDSP_SSR_TYPE_CDC_DOWN
would get received by wcd-dsp-mgr. wcd-dsp-mgr would clear current work and
init wdsp when adsp is up and ready_compl flag is set to ready. Sometimes
ready_compl flag is not cleared and wdsp initialization would happen when
adsp/wdsp is down which would cause kernel panic.
Reinit ready_compl flag when adsp/wdsp SSR happens.
