disp: msm: sde: avoid CWB in power on commit

Browse Source 
This change depends on HAL change which sets CONNECTOR_SET_CRTC
property to null for cwb conn, if cwb is enabled during power off commit.
This causes power off commit crtc_state's active_changed and
connectors_changed set to true, which is causing seamless_crtc
to true during msm_disable_outputs and this leads to invalid crtc
state. This change modifies the seamless_crtc condition and
the msm_crtc_set_mode callback is early returned during such cases
to power off crtc.

Without this change, during power on commit crtc_duplicate_state
is causing cwb to turn on and the release fence is being created with
+2 offset in such case, leading to late release fence signalling and
further GPU fence timeouts.
