kernel/vm: Drop vm_page_num_available_pages.

Browse Source 
Nothing uses it, and it isn't correct anyway: vm_page_num_free_pages()
now includes cached pages, too, while vm_available_memory() includes
not just available memory pages but also swap.

The latter returns the number of pages that are completely uncommitted,
