Subject: [PATCH v2 11/15] soc: qcom: aoss: Use mbox_ring_doorbell() instead of NULL message

As per the patch ("mailbox: Deprecate NULL mbox messages; Introduce
mbox_ring_doorbell()"), we want to switch all users of NULL mailbox
messages to use mbox_ring_doorbell().

This client only ever sent NULL messages, so the transition is
straightforward. We can remove the call to mbox_client_txdone(). The
call didn't do anything for NULL messages and it's now officially
documented not to be called for doorbells.
