cxl/test: Propagate -ENOMEM on platform_device_alloc() failures

Browse source

Set rc = -ENOMEM at every platform_device_alloc() failure site in
cxl_rch_topo_init(), cxl_single_topo_init() and cxl_test_init() so the
failure is propagated and the module load aborts cleanly.

The cxl_acpi allocation site originates in the commit below, while the
host-bridge/root-port/uport/dport allocation sites fixed here were added
later in the single-host and RCH topology configs.

Fixes: 67dcdd4d3b ("tools/testing/cxl: Introduce a mocked-up CXL port hierarchy")
Fixes: e41c8452b9 ("tools/testing/cxl: Add a single-port host-bridge regression config")
Fixes: c9435dbee1 ("tools/testing/cxl: Add an RCH topology")
