    glsl: Catch subscripted calls to undeclared subroutines

    generate_array_index fails to check whether the target of a subroutine
    call exists in the AST, potentially passing around null ir_rvalue
    pointers eventuating in abort/segfault.

    Fixes: fd01840c0bd3 ("glsl: add AoA support to subroutines")
