net: dsa: realtek: use devm_mutex_init for regmap lock

Browse Source 
With CONFIG_DEBUG_MUTEXES enabled, mutex_destroy() needs to be called
before the lock is discarded. Use devm_mutex_init() instead so the
cleanup is handled automatically.

Fixes: 907e772f6f ("net: dsa: realtek: allow subdrivers to externally lock regmap")
