watchdog: Simplify a little the IPI call
In order to remotely restart the watchdog hrtimer, update_timers() allocates a csd on the stack and pass it to __smp_call_function_single(). There is no partcular need, however, for a specific csd here. Lets simplify that a little by calling smp_call_function_single() which can already take care of the csd allocation by itself.
