media: vivid: Fix global-out-of-bounds read in precalculate_color()
vivid_meta_out_process() is setting `brightness`, `contrast`, `saturation`
and `hue` using tpg_s_*(). This is wrong, since tpg_s_*() do not provide
range checks. Using tpg_s_*() here also makes the control framework
out-of-sync with the actual values. Use v4l2_ctrl_s_ctrl() instead.
This issue has been reported by syzbot as an out-of-bounds read bug in
precalculate_color().
