fs/splice: Pull buf->ops->confirm() from splice_from_pipe actors
This patch pulls calls to buf->ops->confirm() from all actors passed
(also indirectly) to splice_from_pipe_feed().
Is avoiding the call to buf->ops->confirm() while splice()ing to
/dev/null is an intentional optimization? No other user does that
and this will remove this special case.
Against current linux.git 6313e3c21743cc88bb5bd8aa72948ee1e83937b6.
