[PATCH] slab: have index_of bug at compile time

I noticed the code for index_of is a creative way of finding the cache
index using the compiler to optimize to a single hard coded number.  But
I couldn't help noticing that it uses two methods to let you know that
someone used it wrong.  One is at compile time (the correct way), and
the other is at run time (not good).
