  BUG: Delay npyiter size check when size may change

When a multi index is tracked and RemoveAxis can be called, the
size of the iterator may still change. This was causing failures
for example for the SVD, because the gufunc machinery requires
a temporarily larger iterator for output allocation.

Thanks to Jaime (jaime.frio at gmail.com) for noting that this is
plausible since the size check can be delayed pretty ok up
until GetIterNext (or similar functions).

Closes gh-4442
