drm/msm/dsi: set cmd dma done mask before triggering cmds

Browse source 
Make sure that cmd dma done mask is set before sending
dma commands. This will make sure that we don't timeout
if the refcnt's are not properly handled. Many oem's
have their own customizations around this which maynot
handle the refcnt's correctly.
