msm: kgsl: Continue stopping GMU if it cannot idle



If the GMU does not idle after the timeout the stop
sequence is aborted. This causes a bug where the RPMh
wake / sleep sequences are not in sync and that leaves
the system in an incorrect state.

Force the system to continue stopping the GMU in either
case to prevent this.
