[PATCH] iio: imu: bno055: Fix some uninitialized variable usage

[Jonathan Cameron]

From: Jonathan Cameron <Jonathan.Cameron@huawei.com>

Switch the ||'d conditions around to ensure we don't check a value
that hasn't been initialized yet.  Also fix a warning due to lack
of visibility that the initialization path will always run by setting
the array index to 0 at definition.

Fixes: 4aefe1c2bd0c ("iio: imu: add Bosch Sensortec BNO055 core driver")
