msm: mdss: check dcs_cmd_by_left for tear_on and tear_off

Browse source 
"dcs_cmd_by_left" indicates that dcs commands can be only sent
for left DSI controller. Tear_on and Tear_off should not be send
to right controller when above flag is set. This change fixes the
tear_on and tear_off APIs with input validation.
