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

The error handling paths in mt8173_afe_runtime_resume() use incorrect
labels, specifically err_i2s1_m and err_i2s2_m.
When clk_prepare_enable() fails, the code jumps to a label that calls
clk_disable_unprepare() on the clock that failed to enable. Instead,
it should call clk_disable_unprepare() on the clock that was successfully
enabled before the failure.

Fix the labels and clk_disable_unprepare() calls to ensure the error
cleanup is handled correctly.

Replace dev_err() with dev_err_probe() to prevent log spam when probe
returns -EPROBE_DEFER.

The errors handled here are already reported by the called functions,
either directly or deeper in the call chain. Therefore, the additional
dev_err() calls are redundant and can be removed.
