[infiniband] Require drivers to specify the number of ports

Require drivers to report the total number of Infiniband ports.  This
is necessary to report the correct number of ports on devices with
dynamic port types.

For example, dual-port Mellanox cards configured for (eth, ib) would
be rejected by the subnet manager, because they report using "port 2,
out of 1".
