This patch enables the watchdog to detect VF FLR when the link state
changes to down, and the default period is 2000us as defined by
IAVF_DEV_WATCHDOG_PERIOD.
In addition, the 'watchdog_period' devargs was added to adjust the watchdog
period(microseconds), or set to 0 to disable the watchdog.

Please also update ice.rst by adding the usage of the new devarg.

This patch enables the watchdog to detect VF FLR when the link state
changes to down, and the default period is 2000us as defined by
IAVF_DEV_WATCHDOG_PERIOD.
In addition, the 'watchdog_period' devargs was added to adjust the watchdog
period(microseconds), or set to 0 to disable the watchdog.
