rust: miscdevice: fix write_iter safety docs

Browse source

The write_iter callback consumes data from the supplied iov_iter and
wraps it as an IovIterSource.

Its Safety docs required a valid iov_iter for writing, but the
implementation and the IovIterSource contract require one that is valid
for reading. Update the docs to match that direction.
