watchdog/core: Get rid of the racy update loop
Letting user space poke directly at variables which are used at run time is
stupid and causes a lot of race conditions and other issues.
Seperate the user variables and on change invoke the reconfiguration, which
then stops the watchdogs, reevaluates the new user value and restarts the
watchdogs with the new parameters.
