[PATCH] ASoC: ti: omap-mcbsp: Remove mixed goto/scoped cleanup handling

[PATCH] ASoC: ti: omap-mcbsp: Remove mixed goto/scoped cleanup handling

[phucduc.bui]

From: bui duc phuc <phucduc.bui@gmail.com>

After converting to guard()/scoped_guard() helpers,
omap_mcbsp_request() still mixes scoped cleanup with
goto based error handling.

Remove the remaining goto based cleanup paths for a more
consistent cleanup flow.
