hw/nvme: Initialize capability structures for primary/secondary controllers

Browse source 
With four new properties:
 - sriov_v{i,q}_flexible,
 - sriov_max_v{i,q}_per_vf,
one can configure the number of available flexible resources, as well as
the limits. The primary and secondary controller capability structures
are initialized accordingly.

Since the number of available queues (interrupts) now varies between
VF/PF, BAR size calculation is also adjusted.
