[patch] fixed memory leak when error E853 happens

[Dominique Pellé]

Hi

Attached patch fixes a memory leak in Vim-7.4.191
whenever error E853 happens. Typing for example
the following erroneous Ex command n times will
leak n blocks:

  :function Foobar(arg1, arg1)

The leak was introduced in Vim-7.3.325.

Regards
Dominique
