The assumptions of these users of drm_dp_dpcd_readb() is that the passed in output buffer won't change in case of error, but this isn't guaranteed. Fix this by treating any error as the lack of the given capability. In case of DP_SINK_DEVICE_AUX_FRAME_SYNC_CAP an error would leave the buffer uninitialized even with the above assumption.
