ASoC: Name iov_iter argument as iterator instead of buffer
While transitioning ASoC code for iov_iter usages, I kept the argument
name as "buf" as the original code. But, iov_iter is an iterator, and
using the name "buf" may be misleading: the crucial difference is that
iov_iter can be proceeded after the operation, hence it can't be
passed twice, while a simple "buffer" sounds as if reusable.
To make the usage clearer, rename the argument from "buf" to "iter".
There is no functional changes, just names.
