In netc_timer_remove(), hardware interrupts are disabled by clearing
TMR_TEMASK before ptp_clock_unregister() is called. This may cause a
race condition during driver unbind that could leave hardware interrupts
active. For example, a concurrent PTP_CLK_REQ_EXTTS ioctl can re-enable
TMR_TEMASK after it has been cleared, leaving a pending hardware
interrupt when the driver unbinds.
