vfio/mlx5: Init QP based resources for dirty tracking

Browse source

Init QP based resources for dirty tracking to be used upon start
logging.

It includes:
Creating the host and firmware RC QPs, move each of them to its expected
state based on the device specification, etc.

Creating the relevant resources which are needed by both QPs as of UAR,
PD, etc.

Creating the host receive side resources as of MKEY, CQ, receive WQEs,
etc.

The above resources are cleaned-up upon stop logging.

The tracker object that will be introduced by next patches will use
those resources.
