Fixes commit c043ec1ca5ba ("iio:buffer: make length types match kfifo
types").
When the length parameter's type was updated in the
`iio_dma_buffer_set_length()` function, the prototype was omitted in the
`include/linux/iio/buffer-dma.h` header.
This causes a build error when running certain CFLAGS configurations that
are a bit more pedantic.
