io_uring: compare cached_cq_tail with cq.head in_io_uring_poll

After e520227("io_uring: allocate the two rings together"), we compare
sq.head with cached_cq_tail to determine does there any cq invalid.
Actually, we should use cq.head.

Fixes: e520227a8307 ("io_uring: allocate the two rings together")
