cmdq_cb_status is an error status. Use the standard error number
instead of cmdq_cb_status to prevent status duplication.

Hmm, I can't remember the reason I didn't pick. But it was definitely
under "todo" label. I will pick it.
BTW, it helps to see Acked-by's from someone working for the h/w vendor.
thanks.

Yongqiang is working for the h/w vendor and have reviewed this series,
does this get any help?

rx_callback is a standard mailbox callback mechanism and could cover the
function of proprietary cmdq_task_cb, so use the standard one instead of
the proprietary one. But the client driver has already used cmdq_task_cb,
so keep cmdq_task_cb until all client driver use rx_callback instead of
cmdq_task_cb.

Current client use 'struct cmdq_pkt' as callback data, so
change 'void *data' to 'struct cmdq_pkt *pkt'. Keep data
until client use pkt instead of data.
