pcm: another weird API abuse
readv() and writev() should _not_ ignore all but the first ->iov_len,
among other things. Really weird abuse of those syscalls - it
expects a vector element per channel, with identical lengths (it
actually assumes them to be identical - no checking is done).
readv() and writev() are really bad match for that. Unfortunately,
userland API is userland API and we can't do anything about them.
Converted to ->read_iter/->write_iter. Please, _please_ don't do
anything of that kind when designing new interfaces.
