msm: mdss: Add error handling support for DCS command APIs

Currently there is no error handling done for DSI DCS command
APIs like mdss_dsi_cmdlist_put. So for ESD thread use cases,
the caller functions of these DCS command APIs do not have error
propagated if the panel read/write commands fail. Hence add support
for error handling for these functions.
