#391 watchdog bite in hm2-stepper config doesn't cause estop

This bug is present in 2.6 (i tested d49f698b). Start one of the hm2-stepper sample configs, then use halcmd to set the watchdog timeout to less than the servo period.

The hm2 driver logs a "timeout dangerously short" warning, followed immediately by a watchdog bite. But the program keeps running in Axis without any apparent problem. I'd expect the machine to estop immediately on hm2 watchdog bite.
