cx18: Simplify the work handler for outgoing mailbox commands
From: Andy Walls <awalls@radix.net>
Simplify the way outgoing work handler gets scheduled to send empty buffers
back to the firmware for use. Also reduced the memory required for scheduling
this outgoing work, by using a single, per stream work object.
Priority: normal
