net/mlx5: E-Switch, Add state to eswitch vport representors
Currently the eswitch vport reps have a valid indicator, which is
set on register and unset on unregister. However, a rep can be loaded
or not loaded when doing unregister, current driver checks if the
vport of that rep is enabled as a flag to imply the rep is loaded.
However, for ECPF, this is not valid as the host PF will enable the
vports for its VFs instead.
Add three states: {unregistered, registered, loaded}, with the
following state changes across different operations:
create: (none) -> unregistered
reg: unregistered -> registered
load: registered -> loaded
unload: loaded -> registered
unreg: registered -> unregistered
Note that the state shall only be updated inside eswitch driver rather
than individual drivers such as ETH or IB.
