slab: implement bulk alloc in SLAB allocator
This patch implements the alloc side of bulk API for the SLAB allocator. Further optimization are still possible by changing the call to __do_cache_alloc() into something that can return multiple objects. This optimization is left for later, given end results already show in the area of 80% speedup.
