In rnpgbe_mbx.c you use `int ret` for this pattern. I think you should unify
this. But I'm more in favour of `err` than `ret`.

No, it maybe called by suspend callback in the future.
Device relative code will be added in rnpgbe_dev_shutdown, and power state
code in rnpgbe_shutdown. This is the same like other driver did
