msm: kgsl: Do not crash on context detach timeout failure
If context wait for global timeouts in detach path there is
no use to process its pending commands. Hence to handle context
detach timeout failure, invalidate the context and remove all
the pending commands from that context. So that other context
commands proceed successfully after the context detach timeout
fault recovery.
