io_uring: fix wrong sequence setting logic
[ Upstream commit 8776f3fa15a5cd213c4dfab7ddaf557983374ea6 ]
Sqo_thread will get sqring in batches, which will cause
ctx->cached_sq_head to be added in batches. if one of these
sqes is set with the DRAIN flag, then he will never get a
chance to process, and finally sqo_thread will not exit.
Fixes: de0617e4671 ("io_uring: add support for marking commands as draining")
