iio: potentiostat: lmp91000: Fix alignment of buffer in iio_push_to_buffers_with_timestamp() 

[ Upstream commit 8979b67ec61abc232636400ee8c758a16a73c95f ]

Add __aligned(8) to ensure the buffer passed to
iio_push_to_buffers_with_timestamp() is suitable for the naturally
aligned timestamp that will be inserted.

Here structure is not used, because this buffer is also used
elsewhere in the driver.
