msm: kgsl: Trigger preemption from preemption complete interrupt

Browse source 
If a high priority context submits while preemption to a lower context
is underway, then preemption to higher context is not triggered until
either we get a GPU command complete interrupt or another workload
from the higher context is submitted. To avoid this latency,
trigger preemption from the preemption complete interrupt.
