mm/slab: improve kmem_cache_alloc_bulk
The kmem_cache_alloc_bulk return value is weird. It returns the number
of allocated objects, but that must always be 0 or the requested number
based on the implementations and the handling in the callers, but that
assumption is not actually documented anywhere, which confuses automated
review tools.
Fix this by returning a bool if the allocation succeeded and adding a
kerneldoc comment explaining the API.
