serial: core: Fix regression when runtime PM is not enabled
Commit 45a3a8ef8129 ("serial: core: Revert checks for tx runtime PM state")
caused a regression for Sun Ultra 60 for the sunsab driver as reported by
Nick Bowler <nbowler@draconx.ca>.
We need to add back the check runtime PM enabled state for serial port
controller device, I wrongly assumed earlier we could just remove it.
