In _minimize_newtoncg(), the first call to terminate() might occur
before the "gfk" variable has been declared, leading to:
NameError: free variable 'gfk' referenced before assignment in enclosing scope
This happens for instance if maxiter is negative as demonstrated in
added test case.
Closes scipy#8241.
