Series iio: let spi drivers return 0 in .remove() | expand

Up to now kxsd9_common_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.
