I think the question is:
Is there a function that will calculate the stream function
if the u and v data have missing values (_FillValue)?
The answer is "no".
However, you could develop your own.
[1] Use uv2vr_cfd tp calculate the vorticity
http://www.ncl.ucar.edu/Document/Functions/Built-in/uv2vr_cfd.shtml
[2] The vorticity is the Laplacian of the streamfunction.
[3] The stream function can be derived by the
method of relaxation.
good luck
