    Fortran: fix bounds-checking errors for CLASS array dummies [PR104908]

    Commit r11-1235 addressed issues with bounds of unlimited polymorphic a=
rray
    dummies.  However, using the descriptor from sym->backend_decl does bre=
ak
    the case of CLASS array dummies.  The obvious solution is to restrict t=
he
    fix to the unlimited polymorphic case, thus keeping the original descri=
ptor
    in the ordinary case.
