remove redundant NULL check in mark functions

Browse source 
gc.c (gc_mark_children)only calls mark_func if the T_DATA ptr is
non-NULL, so avoid redundantly checking for that in each
mark function.

* iseq.c (iseq_mark): remove check for data pointer
* proc.c (binding_mark): ditto
* vm.c (rb_thread_mark): ditto
* vm_trace.c (tp_mark): ditto
