#1330: special.specfun.jdzo array access out of bounds

 The code seems to assume that the caller has declared
         double precision zo(0:NT)
 for calling the function. This is visible e.g. in the fact that otherwise
 the output appears to contain an off-by-one error. (This indexing
 peculiarity also seems to be forgotten in `jnjnp_zeros`.)

 The other initialization statement required to silence Valgrind is
 Adding this seems also to remove the out-of-bounds indexing, and ensure
 correct output.
