    net: fec: cancel perout_timer when PEROUT is disabled

    The PEROUT allows the user to set a specified future time to output the
    periodic signal. If the future time is far from the current time, the FEC
    driver will use hrtimer to configure PEROUT one second before the future
    time. However, the hrtimer will not be canceled if the PEROUT is disabled
    before the hrtimer expires. So the PEROUT will be configured when the
    hrtimer expires, which is not as expected. Therefore, cancel the hrtimer
    in fec_ptp_pps_disable() to fix this issue.
