[patch java]: Avoid looping over the end_params_node in put_decl_node

[Kai Tietz]

Hi,

this patch makes sure we don't walk in put_decl_node of the
end_params_node element.

ChangeLog

2013-03-22  Kai Tietz  <kti...@redhat.com>

        * lang.c (put_decl_node): Don't iterate over end_params_node.

Tested for i686-w64-mingw32, x86_64-w64-mingw32, and
x86_64-unknown-linux-gnu.  Ok for apply?

Regards,
Kai
