recent dhcpcd looping on ppp0

[Frank Kardel <kardel%netbsd.org@localhost>]

The recent dhcpcd version (-current around 20140927) seems to be looping 
on ppp* interfaces.

Sep 28 15:14:11 Andromeda dhcpcd[3259]: ppp0: unknown carrier
Sep 28 15:14:11 Andromeda dhcpcd[3259]: ppp0: carrier_status: 
Inappropriate ioctl for device
Sep 28 15:14:11 Andromeda dhcpcd[3259]: ppp0: unknown carrier
Sep 28 15:14:11 Andromeda dhcpcd[3259]: ppp0: carrier_status: 
Inappropriate ioctl for device
Sep 28 15:14:11 Andromeda dhcpcd[3259]: ppp0: unknown carrier
Sep 28 15:14:11 Andromeda dhcpcd[3259]: ppp0: carrier_status: 
Inappropriate ioctl for device
Sep 28 15:14:11 Andromeda dhcpcd[3259]: ppp0: unknown carrier
Sep 28 15:14:11 Andromeda dhcpcd[3259]: ppp0: carrier_status: 
Inappropriate ioctl for device
....

Any ideas ? This seems to be a regression.
