[PATCH 1/1] io_uring: move io_req_put_rsrc_nodes()

[Pavel Begunkov <asml.silence@gmail.com>]

It'd be nice to hide details of how rsrc nodes are used by a request
from rsrc.c, specifically which request fields store them, and what bits
are signifying if there is a node in a request. It rather belong to
generic request handling, so move the helper to io_uring.c. While doing
so remove clearing of ->buf_node as it's controlled by REQ_F_BUF_NODE
and doesn't require zeroing.
