disp: msm: sde: avoid false error for encoder restore

Browse source 
Below sequence can trigger encoder restore failure due
to cur_master unavailability.
 -> Primary encoder is attached to crtc-0
 -> Primary encoder enters in power collapse state
 -> CWB encoder attached to crtc-0
 -> Atomic_check updates the crtc encoder_mask with
    two encoders.
 -> Prepare_commit triggers power restore
 -> crtc triggers encoder_restore based on encoder_mask

CWB encoder is not enabled at this stage and it will fail
to restore. This patch avoids the error message in this
valid condition.
