IB/mlx5: Add PCI write end padding support
Add the PCI write end padding flag to device_cap_flags enum and set it
during mlx5_ib_query_device so it will be reported to user-space.
During WQ/QP creation, set that capability for WQ/QP if user requested
it and HW supports it.
PCI write end padding modification is not supported for now. There's no
such flag for a QP but for a WQ, create and modify use the same flag.
Return an error if PCI write end padding flag is set during modify_wq.
