[PATCH] slab: Adds two missing kmalloc() checks.

[Luiz Fernando Capitulino <lcapitulino@mandriva.com.br>]

 Adds two missing kmalloc() checks in kmem_cache_init(). The check is worth
because if kmalloc() fails we'll have a nice message instead of a OOPS (which
will make us look for a bug).

 We're using BUG_ON() so that embedded people can disable it.
