  BUG: numpy.ma.polyfit masks NaNs incorrectly

This fixes the incorrect handing of masked NaNs by
``np.ma.polyfit``. Instead of passing the mask into
``np.polyfit`` by setting the weight of the masked
points to zero, the subset of elements of which are
to be fitted are passed instead.

Closes #5591
