`io_rsrc_node` instance won't be shared among different io_uring ctxs, and its allocation 'ctx' is always same with the user's 'ctx', so it is safe to pass user 'ctx' reference to rsrc helpers. Even in io_clone_buffers(), `io_rsrc_node` instance is allocated actually for destination io_uring_ctx. Then io_rsrc_node_ctx() can be removed, and the 8 bytes `ctx` pointer will be removed from `io_rsrc_node` in the following patch. Signed-off-by:
