iio: accel: bma400: Make bma400_remove() return void
When an i2c or spi driver's remove function returns a non-zero error
code nothing happens apart from emitting a generic error message. Make
this error message more device specific and return zero instead in the
remove callbacks. As the return value of bma400_remove() is unused then,
change the function to not yield a return value.
