drm/bridge: lvds-codec: Fix error checking of drm_of_lvds_get_data_mapping()
The drm_of_lvds_get_data_mapping() returns either negative value on
error or MEDIA_BUS_FMT_* otherwise. The check for 'ret' would also
catch the positive case of MEDIA_BUS_FMT_* and lead to probe failure
every time 'data-mapping' DT property is specified.
Fixes: 7c4dd0a266527 ("drm: of: Add drm_of_lvds_get_data_mapping")
