iio: magnetometer: ak8974: Fix runtime PM imbalance on error
When devm_regmap_init_i2c() returns an error code, a pairing
runtime PM usage counter decrement is needed to keep the
counter balanced. For error paths after ak8974_set_power(),
ak8974_detect() and ak8974_reset(), things are the same.
However, When iio_triggered_buffer_setup() returns an error
code, there will be two PM usgae counter decrements.
