Description

The current implementation of the `IntoRawFd` trait doesn't seem to work correctly. When calling `Uffd::into_raw_fd` the method correctly returns the fd, but it also ends up calling `Uffd::drop` which immediately closes the fd.

Research direction

Start at the Uffd::into_raw_fd implementation and compare its ownership behavior with Uffd::drop. Verify the conversion returns the file descriptor without closing it, and confirm the descriptor remains usable after the Uffd value is consumed.
