Further simplify rsrc infrastructure, and make it a little bit faster. The main part is Patch 3, which establishes 1:1 relation between struct io_rsrc_put and nodes, which removes io_rsrc_node_switch() / io_rsrc_node_switch_start() and all the additional complexity with pre allocations. Note, it doesn't change any guarantees as io_queue_rsrc_removal() was doing allocations anyway and could always fail.
