libibverbs: Extend support of NDR rates

NDR(106.25 Gbps) support exposed new data rates:
800 Gbps - NDR 8x.
1200 Gbps - NDR 12x.

Utility methods were updated to support the new rates mentioned above:
1) Rate to mult - Convert the IB rate enum to a multiple of 2.5 Gbps.
2) Rate to mbps - Convert IB rate enum to the mbps value.

In addition, speed_str() of ibv_devinfo was updated to consider the new
NDR rate.
