ASoC: amd: acp: Fix possible deadlock

On error path, function acp_i2s_set_tdm_slot returns without releasing
the lock and this could result in potential deadlocks in the future.

Error reported by sparse:
sound/soc/amd/acp/acp-i2s.c:95:12: error: context imbalance in
'acp_i2s_set_tdm_slot' - different lock contexts for basic block

Fixes: cd60dec ("ASoC: amd: acp: Refactor TDM slots selction based on acp revision id")
