[Patch, Fortran, committed] Fixed one issue with -fcoarray=lib

The issue fixed by the attached test case was that an automatic array 
wasn't properly initialized with -fcoarray=lib. As the code is for 
explicit-size arrays, it isn't reachable for allocatable coarrays. On 
the other hand, for coarrays with SAVE attribute, already the condition 
before should be triggered:
   else if (sym->attr.codimension && TREE_STATIC (sym->backend_decl))

Thus, removing the condition for good should be fine. (Alternatively, 
one could add an "|| !sym->attr.codimension".)

Build and regtested on x86-64-gnu-linux.
Committed as Rev. 211907.
