[PATCH liburing 1/1] tests: don't sleep too much for rsrc tags

[Pavel Begunkov <asml.silence@gmail.com>]

check_cq_empty() sleeps for a second, and it's called many times
throughout the test. It's too much, reduced it to 1ms. Even if there is
a false negative, we don't care and next check_cq_empty() will fail.
