cxl/mem: Make cxl_dvsec_range() init failure fatal
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.
