io_uring: deduplicate freeing linked timeouts
Linked timeout cancellation code is repeated in in io_req_link_next()
and io_fail_links(), and they differ in details even though shouldn't.
Basing on the fact that there is maximum one armed linked timeout in
a link, and it immediately follows the head, extract a function that
will check for it and defuse.
Justification:
- DRY and cleaner
- better inlining for io_req_link_next() (just 1 call site now)
- isolates linked_timeouts from common path
- reduces time under spinlock for failed links
- actually less code
