drm/omap: dispc: disp_wb_setup to check return code
When dispc_wb_setup() calls dispc_ovl_setup_common() it does not
check for failure but instead keeps on partially setting up WB.
This causes the WB H/W to be partially initialized and yield
unexpected behavior.
Make sure return code is successful before proceeding.
