[PATCH 02/15] iio: accel: bmc150: Make bmc150_accel_core_remove() return void

[Uwe Kleine-König <u.kleine-koenig@xxxxxxxxxxxxxx>]

Up to now bmc150_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 i2c and spi remove callbacks is ignored anyway.
