Bluetooth: btmrvl: wait for HOST_SLEEP_ENABLE event in suspend
After BT_CMD_HOST_SLEEP_ENABLE command finishes, driver should wait until getting BT_EVENT_HOST_SLEEP_ENABLE event to complete suspend procedure. Without this patch the suspend handler would return success earlier. By the time when the BT_EVENT_HOST_SLEEP_ENABLE event comes in the controller driver could have already turned off the bus clock. This causes kernel crash or system reboot eventually.
