io_uring: compare cached_cq_tail with cq.head in_io_uring_poll
After 75b28af("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: 75b28affdd6a ("io_uring: allocate the two rings together")
