IB/mlx5: Allocate the per-port Q counter shared when DEVX is supported
The per-port Q counter is some kernel resource and as such may be used by
few UID(s) upon DEVX usage.
To enable using it for QP/RQ when DEVX context is used need to allocate it
with a sharing mode indication to let firmware allows its usage.
The UID = 0xffff was chosen to mark it.
