drm/msm/dp: disable the opp table request even for dp_ctrl_off_link()

dp_ctrl_off_link() was created to handle a case where we received
a cable connect and then get a cable disconnect without the corresponding
dp_display_enable(). For such cases the pixel clock will be off but the
link clock will still be on. dp_ctrl_off_link() handles this case by
turning off the link clock only.

However, the vote removal to the opp table for this case was missed.
Remove the opp table vote in dp_ctrl_off_link().
