charset="utf-8" From: Markus Armbruster Functions that use an Error **errp parameter to return errors should not also report them to the user, because reporting is the caller's job. When the caller does, the error is reported twice. When it doesn't (because it recovered from the error), there is no error to report, i.e. the report is bogus. qemu_rdma_write_one() violates this principle: it reports errors to stderr via qemu_rdma_register_and_get_keys(). I elected not to investigate how callers handle the error, i.e. precise impact is not known. Clean this up: silence qemu_rdma_register_and_get_keys(). I believe the caller's error reports suffice. If they don't, we need to convert to Error instead.
