[PATCH] nvme-pci: refresh visible attrs after being checked

[Eugen Hristev]

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
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` is called, the one that sets up the hmb, in probe
and in reset_work functions.

Fixes: e917a849c3fc ("nvme-pci: refresh visible attrs for cmb attributes")
Fixes: 86adbf0cdb9e ("nvme: simplify transport specific device attribute handling")
