In preparation for the cxl_pci driver to continue operation after cxl_dvsec_range() failure, update cxl_mem to check for negative error codes in info->ranges. Treat that condition as fatal regardless of the state of the HDM configuration since cxl_mem needs positive confirmation that legacy ranges were not established by platform firmware or another agent.
