serial: sc16is7xx: Fix IRQ number check behavior
The logical meaning of the previous version is wrong due to a typo.
If the IRQ equals 0, no interrupt pin is available and polling mode
shall be used.
Additionally, this fix adds a check for IRQ < 0 to increase robustness,
because documentation still says that negative IRQ values cannot be
absolutely ruled-out.
