Fortran: default-initialization and functions returning derived type [PR85750]

Fortran: default-initialization and functions returning derived type [PR85750]

Functions with non-pointer, non-allocatable result and of derived type did
not always get initialized although the type had default-initialization,
and a derived type component had the allocatable or pointer attribute.
Rearrange the logic when to apply default-initialization.
