io_uring: silence variable ‘prev’ set but not used warning
If io_uring.o is built with W=1, it triggers a warning:
io_uring/io_uring.c: In function ‘__io_submit_flush_completions’:
io_uring/io_uring.c:1502:40: warning: variable ‘prev’ set but not used [-Wunused-but-set-variable]
1502 | struct io_wq_work_node *node, *prev;
| ^~~~
which is due to the wq_list_for_each() iterator always keeping a 'prev'
variable. Most users need this to remove an entry from a list, for
example, but __io_submit_flush_completions() never does that.
Add a basic helper that doesn't track prev instead, and use that in
that function.

io_uring: move list helpers to a separate file
It's annoying to have io-wq.h as a dependency every time we want some of
struct io_wq_work_list helpers, move them into a separate file.
