Use a workaround for detached parent in carp_proto_input_c().
A NULL dereference can happen since processing protocol layer is
deffered to a second task. In other words the NET_LOCK() is released
then regrabbed between ip_input() and carp_proto_input().
The same workaround is already in use in carp_output() due to deffered
processing in case of IPsec.
The real fix is to make carp(4) MP-safe and use if_get(9) there, any
taker?
Found & fix tested by Hrvoje Popovski.
