Newer FW reports the SD group size directly in the NIC vport context via the sd_group_size field, gated by the sd_group_size capability. Switch sd_init() to source the group size from there and fall back to the MPIR-based host_buses query only when the cap is absent. sd_group_size might return 1 in some FW configuration. Add explicit check to disable SD creation in this case. While here, rename host_buses to group_size throughout sd.c to follow the new name on capable FW.
