book3s64/hash: Add hash_debug_pagealloc_alloc_slots() function

Browse source

This adds hash_debug_pagealloc_alloc_slots() function instead of open
coding that in htab_initialize(). This is required since we will be
separating the kfence functionality to not depend upon debug_pagealloc.

Now that everything required for debug_pagealloc is under a #ifdef
config. Bring in linear_map_hash_slots and linear_map_hash_count
variables under the same config too.
