mm, sl[aou]b: Use a common mutex definition
Use the mutex definition from SLAB and make it the common way to take a sleeping lock. This has the effect of using a mutex instead of a rw semaphore for SLUB. SLOB gains the use of a mutex for kmem_cache_create serialization. Not needed now but SLOB may acquire some more features later (like slabinfo / sysfs support) through the expansion of the common code that will need this.
