IB/{rdmavt, hfi1, qib}: Self determine driver name

Browse Source 
Currently the HFI and QIB drivers allow the IB core to assign a unit
number to the driver name string.

If multiple devices exist in a system, there is a possibility that the
device unit number and the IB core number will be mismatched.

Fix by using the driver defined unit number to generate the device
name.
