iio: accel: bmi088: Make bmi088_accel_core_remove() return void

Up to now bmi088_accel_core_remove() returns zero unconditionally. Make
it return void instead which makes it easier to see in the callers that
there is no error to handle.

Also the return value of spi remove callbacks is ignored anyway.
