[Patch, Fortran] PR55469 - fix I/O memory leaks in case of failure and iostat= being present

[Tobias Burnus]

I have committed the patch after Janne's approval on IRC  and fresh 
building/regtesting as Rev. 203086. See 
http://gcc.gnu.org/ml/fortran/2012-11/msg00092.html

As suggested by Janne, I will backport it to 4.8 in in a bunch of days.
