qcacld-3.0: Avoid calling idle shutdown many times
Shutdown in suspend phase, idle shutdown timer will be invoked if all adapters closed. And then driver suspend function will return EAGAIN to user space to try suspend again. Idle shutdown will be finished in ~1s. Thus, Idle shutdown timer may be called for many times when user space try suspend again. So, add flag to avoid calling idle shutdown many times.
