drm/xe/guc: Fix for dead CT dump not re-arming

Browse Source 
The state dump on a dead CT incident deliberately disarms itself after
running. This is to prevent a long stream of errors causing continuous
dumps. It was supposed to re-arm itself after a reset, however that
was not happening. The re-arm flag was being set but the worker was
not being run to process that flag. So fix that.
