msm: mdss: Fix mdp3 resume when GC and CCS are both enabled

GC programming utilizes LUT of MDP3. During resume the dirty
flag of CCS if enabled is set. This set value is unset when
LUT is updated during resume. This unsetting prevents further
correct register programming of CCS thereby making the screen
dark permanently. Correcting the conditional logic so that
CCS registers are programmed properly with frame kickoff and
no CCS flags are unset with LUT config upon resume.
