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