[PATCH] iio: chemical: scd30: Use devm_mutex_init() over non-devm mutex_init()

[Maxwell Doose]

The current code uses mutex_init() instead of devm_mutex_init(), which
is incorrect as the rest of the file uses the devm automatic resource
management API. Fix this so that the mutex is set up in the same way as
the rest of the device data structure.
