Subject: [PATCH 1/5] nbft: Fix (struct nbft_info_subsystem_ns).num_hfis
off-by-one
The num_hfis field only reflected the number of Secondary HFI
Associations, resulting in the last parsed HFI being ignored
by users (nvme-cli).
According to the NVM Express Boot Specification, Revision 1.0,
the Primary HFI Descriptor Index in the Subsystem Namespace
(SSNS) Descriptor contains this note:
"If multiple HFIs are associated with this record, subsequent
interfaces should be populated in the Secondary HFI
Associations field."
As both the primary and secondary HFIs are parsed into a single
array, it makes sense to reflect the proper number of elements.

Subject: [PATCH 2/5] nbft: avoid duplicate entries in ssns->hfis
The NVMe boot specification does not disallow listing the primary
HFI index again in the secondary HFI list, or listing the same
index multiple times in the secondary HFI list. But such duplicate
entries aren't helpful for consumers of this data. In the worst
case, they might lead to confusion and misconfiguration.
Suppress them.

Subject: [PATCH 3/5] tests: Fix diffs output for duplicate HFI entries
With commit "nbft: avoid duplicate entries in ssns->hfis" applied,
nbft-dump will not see any duplicate HFI indices any more.
Fix the reference output for generating the diffs.
