device: ppp: check that connection has a PPPoE parent

NMDevicePPP only handles connections with the pppoe.parent property
set. match_connection() already checks this when we creating a new
device. We should also perform the same check in
check_connection_compatible().

Fixes: 6c3195931e ('core: implement activation of PPP devices')
