man pages: update non-blocking send descriptions

As noted by Alexander Pozdneev, non-blocking sends are now able to
*access* buffers in pending non-blocking send operations; the buffers
just can't be *modified*.

 Almost all MPI routines return an error value; C routines as the value of the function and Fortran routines in the last argument. C++ functions do not return errors. If the default error handler is set to MPI::ERRORS_THROW_EXCEPTIONS, then on error the C++ exception mechanism will be used to throw an MPI::Exception object.
