FreeBSD: Simplify INGLOBALZONE

Browse Source 
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.
