drm/msm: perform mode fixup against current state

瀏覽代碼 
Current mode fixup validates mode against both state mode and crtc mode
which causes mismatch between validation and drm_mode_equal check.
Perform validation against the same mode (crtc->state->mode) to avoid
mismatch and reflect proper state.
