Set uid as part of various IB commands so that the firmware can manage
the IB object in a secured way.
This series deals with FS core and commands used by the Ethernet driver
  net/mlx5: Update mlx5_ifc with DEVX UID bits
  net/mlx5: Set uid as part of CQ commands
  net/mlx5: Set uid as part of RQ commands
  net/mlx5: Set uid as part of SQ commands
such as the life-cycle (create, modify, destroy) of objects like:
RQ/SQ/CQ/etc --
saying IB commands is inaccurate, please be more precise

The firmware should mark this IB object with the given uid so that it
can be used later on only by objects with the same uid.
these are not IB objects, but rather Ethernet objects
Upon DEVX flows that use this objec, the pointed object must have
the same uid as of the issuer uid command.
typo - objec --> object
When a command is issued with uid=0 it means that the issuer of the
command is trusted (i.e. kernel), in that case any pointed object
can be used regardless of its uid.
