don't try and free what must be a null vector when reserving 0 elements
in va_heap::reserve
2013-11-05 Trevor Saunders <tsaunders@mozilla.com>
* vec.c (vec_prefix::calculate_allocation): Don't try to handle the
case of no prefix and reserving zero slots, because when that's the
case we'll never get here.
* vec.h (va_heap::reserve): Don't try and handle
vec_prefix::calculate_allocation returning zero because that should
never happen.
