[SERIAL] Fix UPF_ flag usage with uart_info->flags
The previous change found a bug in the serial SAK handling - because we were looking for UPF_SAK set in uart_info->flags, we would never raise a SAK condition. UPF_SAK is in uart_port->flags. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
