_setup_new_thread: fix crash on ARM
On arches which have custom logic to do the initial swap into
the main thread, _current may be NULL. This happens when
instantiating the idle and main threads.
If this is the case, skip checks for memory domain and object
permission inheritance, in this case there is never anything to
inherit.
