drm/bridge: anx7625: Propagate errors from sp_tx_edid_read()

Browse Source 
During the sp_tx_edid_read() call the return value of sp_tx_edid_read()
is ignored, which could cause potential errors to go unhandled.

All errors which are returned by sp_tx_edid_read() are handled in
anx7625_get_edid().
