[PATCH 2/2] staging:iio: Remove noop calls to __iio_update_buffer

[Lars-Peter Clausen <lars@metafoo.de>]

__iio_update_buffer updates the buffer's bytes_per_datum and length attributes.
But in these two cases we indirectly just pass the existing values, so the call
becomes a noop and can be removed.

We might as well also remove the function itself, since these are the only two
users. What do you think?
