Subject: [PATCH] idr test suite: Fix ida_test_random()
The test was checking the wrong errno; ida_get_new_above() returns
EAGAIN, not ENOMEM on memory allocation failure. Double the number of
threads to increase the chance that we actually exercise this path
during the test suite (it was a bit sporadic before).
