qcacld-3.0: Enable delayed peer obj freed feature in the default config

Define the CONFIG_FEATURE_DELAYED_PEER_OBJ_DESTROY to enable peer obj
freed in a delayed work item to avoid any potential scheduling in the
atomic context.

It might invoke wakeup_source_unregister in the peer obj destroy handler
which happens in the atomic context to cause scheduling timeout issue.

Here is the call trace without enabling this flag:
