mm: drop "wait" parameter from write_one_page()
The callers all set it to 1. Also, make it clear that this function will not set any sort of AS_* error, and that the caller must do so if necessary. No existing caller uses this on normal files, so none of them need it. Also, add __must_check here since, in general, the callers need to handle an error here in some fashion.
