[PATCH v2] watchdog: core: make sure the watchdog worker always works

When running a command like 'chrt -f 50 dd if=/dev/zero of=/dev/null', the watchdog_worker fails to service the HW watchdog and the HW watchdog fires long before the watchdog soft timeout. At the moment, the watchdog_worker is invoked as a delayed work. Delayed works are handled by non realtime

Getting kernel 4.14 to run on PS3
