current_num_pages is the number of pages balloon has right now.
requested_num_pages is the desired number of pages in the balloon.
'current_num_pages' corresponds to the 'actual' virtio-balloon config field
'requested_num_pages' corresponds to the 'num_pages' virtio-balloon config field.
void RequestNumPages (uint32_t requested_num_pages)Request a number of pages to be supplied to the memory balloon.
If `requested_num_pages` is greater than the `current_num_pages` config
value, the guest driver SHOULD provide additional pages to the memory balloon.
