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.
