iio: tmag5273: Fix runtime PM leak on measurement error
The tmag5273 gets a runtime PM reference before reading a measurement and
releases it when done. But if the measurement fails the tmag5273_read_raw()
function exits before releasing the reference.
Make sure that this error path also releases the runtime PM reference.
