For the CMB attributes, commit e917a849c3fc ("nvme-pci: refresh visible attrs for cmb attributes") solved this problem by calling nvme_update_attrs after mapping the CMB. However the issue persists for the HMB attributes. To solve the problem, moved the call to nvme_update_attrs after nvme_setup_host_mem, which sets up the HMB.
