On WCN6750 platforms, QRTR SMD may not be available when ath11k starts
during boot. If QMI messages never arrive, WLAN initialization can stall,
leaving firmware running but no wireless interface created.

It also hardens the cleanup path to avoid crashes when deinitializing
partially initialized devices after QMI setup failures.
