Subject: [PATCH] Fix a new beta clippy warning

warning: unused return value of `std::boxed::Box::<T>::from_raw` that must be used
  --> gstreamer-rtsp-server/src/rtsp_session_pool.rs:23:5
   |
23 |     Box::<F>::from_raw(ptr as *mut _);
   |     ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
   |
   = note: `#[warn(unused_must_use)]` on by default
   = note: call `drop(from_raw(ptr))` if you intend to drop the `Box`
