ext/socket/ifaddr.c: remove empty ifaddr_mark

Browse source 
We do not need to maintain empty functions for GC,
gc_mark_children will not attempt to dereference NULL
dmark callbacks.

* ext/socket/ifaddr.c (ifaddr_mark): remove empty function
  (ifaddr_type): pass zero to rb_data_type_t.function.dmark
