From: Konstantin Taranov <kotaranov@microsoft.com>
Add helpers to retrieve the send and receive queues of a QP.
Use these helpers when storing queue IDs in the lookup table.
MANA queue IDs are 2-bit aligned, allowing the two least
significant bits to be omitted when storing and looking up
queue IDs.

From: Konstantin Taranov <kotaranov@microsoft.com>
Implement UC QP creation in the RNIC HW for user API.
An UC QP is exposed as three work queues: send, receive,
and memory management. The latter is used for bind and
invalidate WQEs to support memory windows.
