libcamera: gst: Fix double-free when acquire_buffer fails
If gst_buffer_pool_acquire_buffer in gst_libcamera_task_run fails, the unique_ptr to the request-object gets reset and hence, its destructor is called. However, the wrap-object points to the same object and is still alive at this moment. When the task_run-function is finished, the destructor of the wrap-object is called, which in return calls the destructor of the request-object again. Instead of taking care of both, the request and the wrap-object, we can move the request to the wrap which will then effectively take care of the request object automatically.
