disp: msm: dsi: Fix post cmd tx sequence for read commands

Browse Source 
For read commands, wait_for_done() should be called in dsi_message_rx function.
Currently, its being called twice from dsi_message_rx and dsi_ctrl_post_cmd_transfer.
This change adds a check to skip wait_for_done() from dsi_ctrl_post_cmd_transfer.
