io_uring: add new helpers for posting overflows
Add two helpers, one for posting overflows for lockless_cq rings, and
one for non-lockless_cq rings. The former can allocate sanely with
GFP_KERNEL, but needs to grab the completion lock for posting, while the
latter must do non-sleeping allocs as it already holds the completion
lock.
While at it, mark the overflow handling functions as __cold as well, as
they should not generally be called during normal operations of the
ring.
