drivers: mailbox: retry message submission 



msg_submit() bails if there are no requests in the mailbox queue or if
there is an valid active request that is pending a tx_done response. If
the controller had returned -EAGAIN when trying to send data, the
framework should unlock the spinlock and retry sending the request to
the controller.
