Ilpo Järvinen 596a917147 serial: Clear rs485 struct when non-RS485 mode is set 
When SER_RS485_ENABLED is not set, having any other flag/field set in
serial_rs485 struct does not have an effect different from not having
them set. Thus, make the serial_rs485 struct also match the behavior
for all flags, not just SER_RS485_ENABLED.

Some drivers do similar clearing of rs485 struct in their
rs485_config() already, but not all. This change makes the behavior
consistent across drivers.

Don't try to validate rs485 struct further when no RS485 is requested,
this silences some bogus warnings.

This change has (minor) userspace visible impact.
