[PATCH v7 10/13] drm/xe/guc_submit: Allow calling guc_exec_queue_resume with pending resume

[Francois Dugast]

Make it safe to have multiple calls to guc_exec_queue_resume() for the
same exec queue. This allows the use of this function from a context where
knowledge about prior calls is missing. In this case the function does
nothing but at least it does not fail on assert.
