mm: make gather_stats() type-safe and remove forward declaration
Improve the prototype of gather_stats() to take a struct numa_maps as
argument instead of a generic void *. Update all callers to make the
required type explicit.
Since gather_stats() is not needed before its definition and is scheduled
to be moved out of mempolicy.c the declaration is removed as well.
