[PULL 18/21] migration/multifd: use pages->allocated instead of the static max

[Dr. David Alan Gilbert (git)]

From: Wei Yang <richardw.y...@linux.intel.com>

multifd_send_fill_packet() prepares meta data for following pages to
transfer. It would be more proper to fill pages->allocated instead of
static max value, especially we want to support flexible packet size.
