[PATCH 1/1] io_uring: fix drain alloc fail return code

[Pavel Begunkov <asml.silence@xxxxxxxxx>]

After a recent change io_drain_req() started to fail requests with
result=0 in case of allocation failure, where it should be and have
been -ENOMEM.

Fixes: 76cc33d79175a ("io_uring: refactor io_req_defer()")
