drm/amdkfd: Fix race in GWS queue scheduling
q->gws is not updated atomically with qpd->mapped_gws_queue. If a
runlist is created between pqm_set_gws and update_queue it will
contain a queue which uses GWS in a process with no GWS allocated.
This will result in a scheduler hang.
Use q->properties.is_gws which is changed while holding the DQM lock.
