Resolve all kernel-doc warnings in buffer_impl.h:

Warning: include/linux/iio/buffer_impl.h:172 struct member 'direction' not described in 'iio_buffer'
Warning: include/linux/iio/buffer_impl.h:184 No description found for return value of 'iio_update_buffers'

Also correct one typo (word order switch).
