  [flang][cuda] Avoid crash by exiting the check if assignment is not usable (#89149)

In the presence of other semantic error, `GetAssignment` would return a
nullptr and therefore would make the rest of the check crash when trying
to collect symbols.

Exiting early when we have a nullptr so the compiler doesn't crash and
user can get the meaningful semantic error.
