Confirm the region exists upon load of the cxl-test module. Signed-off-by: Alison Schofield --- The region does survive the ensuing shenanigans of this test. The region state moves from committed to disabled and back again as the memdevs, ports, and host bridges are disabled and then re-enabled. Although that was interesting, it's not clear that this test should be doing region error recovery testing.
