[PATCH v2 12/19] iio: chemical: bme680: Allocate IIO device before chip initialization

[Vasileios Amoiridis]

Move the IIO device allocation before the actual initialization
of the chip to be more consistent with most IIO drivers and also
to have the ability to use any driver specific data for the chip
initialization.

While at it, fix also a misaligned line.
