msm: mdss: Move histogram completion initialization to pp_init 



The histogram completion structures are initialized in pp_init, in
order to avoid the wait_queue initialization being called multiple times.
The init_completion in hist_enable has been replaced with a safer
function that does not modify the wait_queue.
