Subject: IB/{rdmavt, hfi1, qib}: Remove get_card_name() downcall
Patch-mainline: v4.16-rc1
Git-commit: 06f2597f75c7ecd9006dd9711ec8c09b4f3d29e3
References: bsc#1114685 FATE#325854

rdmavt has a down call to client drivers to retrieve a crafted card
name.

This name should be the IB defined name.

Rather than craft the name each time it is needed, simply retrieve
the IB allocated name from the IB device.

Update the function name to reflect its application.

Clean up driver code to match this change.
