msm: kgsl: Don't consider active count if not in active state

Don't consider active_cnt variable if not already in ACTIVE state.
The active count variable does not necessarily exactly indicate the
number of open handles to GPU for switching power state. Hence,
only wait for active count to reach zero before switching to SUSPEND
state if, the current state is ACTIVE.

msm: kgsl: Always resume the GPU regardless of its state

Make sure we resume the GPU regardless of its current
state. If the device is not in suspend state restart the
device and  print an error message.
