staging:iio:adis16130: Fix sample reading 

The driver first does a proper read of the data register, but right after that
it does a spi_read, which will overwrite the initial result.

It looks as if the extra spi_read was accidentally introduced in commit
a5e7363ca ("staging:iio:gyro:adis16130 drop control of adc resolution."), quite
likely due to a bad rebase.
