[PATCH] slab: Remove cache_chain_lock

Manfred added a new lock to protect the global list of slab caches.  We
already have a semaphore from those but he needs locking from timer
context.

So here we remove that lock and just do a down_trylock() on the
existing semaphore.  If that fails give up - we'll try again next timer
tick.
