FreeBSD's previous ZFS implemented INGLOBALZONE(thread) as (!jailed((thread)->td_ucred)) and passed curthread to INGLOBALZONE. We pass curproc instead of curthread, so we can achieve the same effect with (!jailed((proc)->p_ucred)). The implementation is trivial enough to fit on a single line in a define. We don't really need a whole separate function for something that's already macros all the way down. Eliminate in_globalzone.
