[PATCH 1/1] io_uring/rw: reissue only from the same task

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

io_rw_should_reissue() tries to propagate EAGAIN back to io_uring when
happens off the submission path, which is when it's staying within the
same task, and so thread group checks don't make much sense.
