ASoC: rockchip: Drop problematic guard() changes

This reverts commit f7fe9f707360 ("ASoC: rockchip: rockchip_sai: Use
guard() for spin locks").

This is very noisy pointless churn that was not tested by the submitter,
nor was it addressed to the driver's maintainer. It mixes unrelated
whitespace changes (eliminating the blank line between the includes -
why?) with hard to review diffs that add a whole indentation level to
the function for no benefit, while also not following kernel code style
by doing stuff like "ret == 0".

The driver is better off without these changes, and they're not worth
the time to validate whether they really do make no functional changes.
