[PATCH for-rc v3] RDMA/restrack: Track driver QP types in resource tracker

[Gal Pressman <galpress@amazon.com>]

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")
