io_uring: ensure local task_work is run on wait timeout
commit 6ff1407e24e6fdfa4a16ba9ba551e3d253a26391 upstream.
A previous commit added an earlier break condition here, which is fine if
we're using non-local task_work as it'll be run on return to userspace.
However, if DEFER_TASKRUN is used, then we could be leaving local
task_work that is ready to process in the ctx list until next time that
we enter the kernel to wait for events.
Move the break condition to _after_ we have run task_work.
