PING**(5./7.) [patch, fortran] Fix memory leaks for finalized types

[Thomas Koenig via Gcc-patches]

Hello world,

this patch fixes a 8/9/10/11 regression, where finalized types
were not finalized (and deallocated), which led to memory
leaks.

Hi,

OK for trunk? The patch is simple enough (and the regression bad enough)
that I'll commit on Sunday unless there are any objections.

Regards

        Thomas
