This never happens, it is dead code, right?

This is all confused, the adev->name is supposed to be a compile time
constant, this not be allocating memory and combining the constant
"intel_rdma" and the trailing "iwarp" "roce"
Just use the proper define right here.
Also all these kasprintfs should have their errors checked, which is
also why it shouldn't be written like this.
