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.
