[PATCH i-g-t v2 2/2] /tests/intel/xe_eudebug_online: Remove vm_open_trigger on debugger reattachment.

[Jan Sokolowski]

On debugger detach-and-reattach, discovery worker will replay events
that have occurred, which leads to a vm event being sent and
vm_open_trigger being re-run, which would lead to us trying
to open a removed vm.

On debugger reattach trigger, remove vm open trigger from list of
triggers.
