cpufreq: loongson3: Check for error code from devm_mutex_init() call
[ Upstream commit db01e46689e9a986ca6b5d2f41b57d7a81551a4f ]
Even if it's not critical, the avoidance of checking the error code
from devm_mutex_init() call today diminishes the point of using devm
variant of it. Tomorrow it may even leak something. Add the missed
check.
