hwmon: (ina2xx) Acquire hwmon_lock in shunt_resistor_show()

Browse source

shunt_resistor_store() currently acquires hwmon_lock to set
data->rshunt, but the corresponding access in shunt_resistor_show() is
unprotected. Acquire the lock in shunt_resistor_show() as well to ensure
proper synchronization.
