net/mlx5: SD, prefer sd_group_size from vport context
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.
