The platform may not support fastchannel, but this is a legal
operation.

        -Before this patch, when the platform not support fastchannel,
        goto err_xfer will print "Failed to ...". This log is misleading.

        -With this patch, when the fastchannel is not been supported,
        the "Failed to ..." log will be skipped.
