During suspend/resume process all connectors are explicitly disabled and
then reenabled. However resume fails because of the connector_status check:
[ 1185.831970] [dpu error]connector not connected 3
It doesn't make sense to check for the Writeback connected status (and
other drivers don't perform such check), so drop the check.
Fixes: 71174f362d67 ("drm/msm/dpu: move writeback's atomic_check to dpu_writeback.c")
