target/ppc: Handle AIL=0 in ppc_excp_vector_offset

The exception vector offset calculation was moved into a function but
the case when AIL=0 was not checked.

The reason we got away with this is that the sole caller of
ppc_excp_vector_offset checks the AIL before calling the function:

    /* Handle AIL */
    if (ail) {
        ...
        vector |= ppc_excp_vector_offset(cs, ail);
    }
