Jens Axboe 38cfdd9dd2 io_uring/fdinfo: be a bit nicer when looping a lot of SQEs/CQEs 
Add cond_resched() in those dump loops, just in case a lot of entries
are being dumped. And detect invalid CQ ring head/tail entries, to avoid
iterating more than what is necessary. Generally not an issue, but can be
if things like KASAN or other debugging metrics are enabled.
