The check for QP type different than XRC has wrongly excluded driver QP
types from the resource tracker.
As a result, "rdma resource show" user command would not show opened
driver QPs which does not reflect the real state of the system.
Check QP type explicitly instead of improperly assuming enum
values/ordering.
