This commit changes `Message::Write()` to return `void` instead of returning the number of bytes written. The `Write()` method does not resize the message and requires that the given data can be fully written into the message within its existing length. The `Write()` already contains an `OT_ASSERT()` to verify this. This commit also removes the redundant `OT_ASSERT()` checks in few places where `Write()` method's returned value was being used.
