IB/uverbs: Add WQ support
User space applications which use RSS functionality need to create
a work queue object (WQ). The lifetime of such an object is:
* Create a WQ
* Modify the WQ from reset to init state.
* Use the WQ (by downstream patches).
* Destroy the WQ.
These commands are added to the uverbs API.
