qcacld-3.0: Add NL event to indicate SSR shutdown is triggered

Browse source 
propagation from qcacld-2.0 to qcacld-3.0.

On Dual-WiFi Platforms, Radio Device 1 (R1 - SDIO interface) should
be functional only if Radio Device 0 (R0 - PCIe interface) is active.
If SSR is indentified on R0, indicate userspace application to unload
R1 on this event and Reload R1 once R0 SSR and reload is complete.
