Don't say that the nointr allocator happens to be interrupt safe since
that's something that callers shouldn't know and it just confuses people.

If you want an interrupt safe allocator you specify NULL as the last
argument to pool_init(). If you want a no interrupt allocator you use
_nointr. The fact that they happen to be the same right now is irrelevant.
