Remove code that isn't reached. There is no need to check for adapter->req_vec_chunks, because if it isn't set idpf_set_mb_vec_id() won't be called. Only one path when idpf_set_mb_vec_id() is called: idpf_intr_req() -> idpf_send_alloc_vectors_msg() -> adapter->req_vec_chunk is allocated here, otherwise an error is returned and idpf_intr_req() exits with an error. The idpf_set_mb_vec_id() becomes one-liner and it is called only once. Remove it and set mailbox vector index directly.
