remove branches in dmark and dfree GC callbacks

dmark and dfree callbacks are never called in gc.c for NULL
DATA_PTR values, not even for zombie objects.

* compile.c (ibf_loader_mark): remove branch for pointer validity
* compile.c (ibf_loader_free): ditto
* cont.c (cont_free): ditto
* cont.c (fiber_free): ditto
* dir.c (dir_free): ditto
* ext/stringio/stringio.c (strio_mark): ditto
* proc.c (binding_free): ditto
* thread_sync.c (mutex_free): ditto
* vm.c (thread_free): ditto
