Avoid getting the same default zone twice in a row.

Browse Source 
847ff22 added a call to malloc_default_zone() before the main loop in
register_zone, effectively making malloc_default_zone() called twice
without any different outcome expected in the returned result.

It is also called once at the beginning, and a second time at the end
of the loop block.

Instead, call it only once per iteration.
