libc - Fix livelock in nmalloc

* free() -> _slabfree() was turning around and calling _slaballoc()
  with the depot lock held, which could lead to a livelock.  Fix by
  unlocking the depot lock around the call.

* Clean up and document other unrelated bits of nmalloc(). In particular,
  clean up magazine_alloc().
