msm: kgsl: Avoid false GMU alarm due to preemption

Do not allow rescheduling if GMU responds to driver requests
within a millisecond in normal cases. Increase HFI receiving
message timeout value to allow GMU watchdog interrupt to happen
before driver alarms. GMU watchdog interrupt provides more GMU
relevant debugging information.
