ASoC: cs35l41: Handle mdsync_down reg write errors

[ Upstream commit a9a3f54a23d844971c274f352500dddeadb4412c ]

The return code of regmap_multi_reg_write() call related to "MDSYNC
down" sequence is shadowed by the subsequent
wait_for_completion_timeout() invocation, which is expected to time
timeout in case the write operation failed.

Let cs35l41_global_enable() return the correct error code instead of
-ETIMEDOUT.
