net/mlx5: Fix multiport device check over light SFs
[ Upstream commit 47bf2e813817159f4d195be83a9b5a640ee6baec ]
Driver is using num_vhca_ports capability to distinguish between
multiport master device and multiport slave device. num_vhca_ports is a
capability the driver sets according to the MAX num_vhca_ports
capability reported by FW. On the other hand, light SFs doesn't set the
above capbility.
This leads to wrong results whenever light SFs is checking whether he is
a multiport master or slave.
Therefore, use the MAX capability to distinguish between master and
slave devices.
