[ Upstream commit 52e0a118a20308dd6aa531e20a5ab5907d2264c8 ]
The check for QP type different than XRC has 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 assuming enum values/ordering.
Fixes: 40909f664d27 ("RDMA/efa: Add EFA verbs implementation")
