nvme-pci: refresh visible attrs after being checked

Browse Source 
The sysfs attributes are registered early, but the driver does not know
whether they are needed or not at that moment.

For the CMB attributes, commit e917a849c3 ("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.

Fixes: e917a849c3 ("nvme-pci: refresh visible attrs for cmb attributes")
Fixes: 86adbf0cdb ("nvme: simplify transport specific device attribute handling")
