qcacld-3.0: Add ini to raise bug on SSR re-init failure

Browse source 
qcacld-2.0 to qcacld-3.0 propagation

Currently, If SSR re-init get failed then host raise VOS_BUG.
In this type of cases, OEM might prefer not to crash the device
instead want wlan recovery using driver unload followed by load.
