Dmitry Baryshkov f0e7e9ed37 drm/msm/dsi: fix error checks and return values for DSI xmit functions
As noticed by Dan ([1] an the followup thread) there are multiple issues
with the return values for MSM DSI command transmission callback. In
the error case it can easily return a positive value when it should
have returned a proper error code.

This commits attempts to fix these issues both in TX and in RX paths.
