qcacld-3.0: Fix compilation error when shadow config v3 is unsupported

For targets not supporting shadow config v3, the compilation
may fail since the definition for shadow config v3 will not
be available.

Featurize the shadow config v3 properly to avoid any
compilation errors for targets not supporting this feature.
