msm: kgsl: Don't halt dispatcher if device is not in SUSPEND state
Add a check to make sure device actually transitioned to SUSPEND
state before halting dispatcher in adreno_suspend_device function.
kgsl_pwrctrl_change_state(device,KGSL_STATE_SUSPEND) in
kgsl_suspend_device can return zero without actually changing state
to SUSPEND if device state is NONE or INIT.
