With the current version of GSL (without the patch), the user do not get a
chance to check the return status of gsl_interp2d_eval_e() because GSL_ERROR()
gets called direclty instead of returning an error code as advertised in the
documentation.
With the changes I propose, the domain error will still be caught by macro
DISCARD_STATUS() that checks the return code of gsl_interp2d_eval_e() in
gsl_interp2d_eval() but the intended behavior for gsl_interp2d_eval_e() will
be achieved. The only downside I see with this patch is that the user now
gets an out-of-domain error but he is not told anymore whether the error was
caused by the x or the y coordinate.
